In order to improve the self-adjusting ability of the constant temperature control system of the dough mixer, we have carried out many experimental analyses and finally come to the conclusion that the fuzzy self-adaptive PID algorithm can effectively improve the constant temperature system of the dough mixer. Traditional PID algorithm is composed of proportional unit P, integral unit I and differential unit D. Once the parameters P, I and D are established, they cannot be changed. Therefore, this algorithm has a weak adaptive ability and cannot be changed according to the environment. The fuzzy adaptive PID algorithm used in this paper refers to the input error e(t) and error change rate ec(t). Fuzzy reasoning is carried out by using fuzzy rules, and the fuzzy matrix table is consulted to meet the adaptive adjustment of PID parameters at different times, so as to achieve the adaptive PID algorithm. For the temperature control system of dough mixer, PID algorithm and fuzzy adaptive PID algorithm are used to construct the constant temperature system respectively. Based on the specific environment of the dough mixer, after three times of comparative experimental analysis, the final conclusion is that the fuzzy self-adaptive PID algorithm overshoot is small, which can reach the stable range faster, and the accuracy is improved by 0.6% compared with the traditional PID algorithm.","PeriodicalId":105852,"journal":{"name":"Proceedings of the 2019 International Conference on Robotics, Intelligent Control and Artificial Intelligence","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132541438","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the development of artificial neural network research, the recognition and tracking algorithm based on neural network has been greatly improved in recognition speed and accuracy. But its performance depends greatly on the training database, and the amount of calculation is too large to meet the real-time requirements. The tracker based on correlation filtering is fast, but it will lose the target once the target is slightly occluded. In this paper, we proposed an improved algorithm based on CamShift and Kalman filter. Through the prediction function of Kalman filter, reduce the range of search window of CamShift. Then the target information obtained by CamShift algorithm is fed back to Kalman filter for updating and correction. The optimization algorithm not only satisfies the real-time requirement of video target tracking, but also improves the tracking accuracy even if the target is overshadowed.","PeriodicalId":105852,"journal":{"name":"Proceedings of the 2019 International Conference on Robotics, Intelligent Control and Artificial Intelligence","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127018511","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Firstly, the finite element model of the battery box was established by using ABAQUS. The battery box was geometrically cleaned, the composite material of the box structure and the foam material of the battery module were defined, and the grid was divided according to the process of finite element analysis. Then, based on the actual application, the boundary conditions were set and the load was applied to solve the problem. Finally, the stress and failure factor of the composite battery box under the sudden braking and sharp turn of the bumpy road were analyzed, and the strength of the battery box was checked. The results show that under the two combined conditions, the maximum stress of the battery box is less than the specified stress of the composite material, and the failure factor is much less than 1, meeting the strength requirements of the battery box.","PeriodicalId":105852,"journal":{"name":"Proceedings of the 2019 International Conference on Robotics, Intelligent Control and Artificial Intelligence","volume":"468 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133212984","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The structural design principle of the inertial protection mechanism and its two different configuration in two working modes are analyzed through the mechanism sketch.

A simulated vehicle detection standard is used as an initial condition for dynamic simulation of the inertial protection mechanism. The simulation results show that the inertial protection mechanism can be switched to the inertia protection mode in 0.2ms, The mechanism ensures the safety of the passengers inside the vehicle by overcoming the risk of the side door accidentally open when the vehicle is hit by the side.","PeriodicalId":105852,"journal":{"name":"Proceedings of the 2019 International Conference on Robotics, Intelligent Control and Artificial Intelligence","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133219976","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The liquefaction may occur suddenly and cause a dangerous list or even capsize of the vessel. In order to evaluate the liquefaction potential of the mineral ores during ocean shipping, this paper established a liquefaction risk assessment model for mineral ores through Analytical Hierarchy Process (AHP). An evaluation index system of liquefaction risk was constructed into an orderly hierarchical structure. Three crucial factors including vibration acceleration, moisture content and fine particles, were pairwise compared during the process. The order of the priority weight for the factors was moisture content (0.5834) > vibration acceleration (0.333) > fine particles content (0.0833). The risk value and value range of each factor were assigned on a five-point scale. Consequently, the overall value of the liquefaction risk was computed and the corresponding likelihood of liquefaction occurrence was assessed and validated. The liquefaction risk assessment model of bulk mineral ores was reasonable, which could provide useful information to avoid liquefaction of bulk mineral ores.","PeriodicalId":105852,"journal":{"name":"Proceedings of the 2019 International Conference on Robotics, Intelligent Control and Artificial Intelligence","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123775947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, controlling and compensating for contour errors is of great significance. This paper applies the D-H method in robot kinematics to the error modeling of CNC machine tools, and this paper takes the double turntable five-axis machine tool as the research object. In this paper, by establishing a kinematics positive solution model, the law of the contour error of the tool tip and the contour error of the tool orientation are revealed, which provides a theoretical basis for the contour error compensation control. Based on this, a contour error compensation control method is designed. Simulation experiments show that the control method can effectively reduce the contour error.","PeriodicalId":105852,"journal":{"name":"Proceedings of the 2019 International Conference on Robotics, Intelligent Control and Artificial Intelligence","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114518223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper was based on the portable fast battery diagnostic instrument, which quickly checked the lithium iron phosphate battery packs with different degrees of aging to determine whether the battery management system and the battery modules were connected properly. Furthermore, the constant current discharge curve of the battery was analyzed, and the internal resistance of each single cell in the battery module was obtained, thereby characterizing the difference in the aging degree of different single cells. Finally, the same battery module was tested using a portable fast battery diagnostic device. The verification found that after the battery management system and the single battery connection problem were eliminated, the portable device obtained the same result under different detection conditions, and the battery module was aged. The single cell was judged to be a problematic single cell because the internal resistance was too large and the open circuit voltage was too low. The portable device has low cost, simple operation, convenient and fast, and is suitable for rapid troubleshooting and internal resistance detection of the battery module in the field, and does not affect the life of the battery pack itself. The results of the fast battery diagnostic process are reliable and can provide a reference for the promotion of the rapid diagnosis of power batteries.","PeriodicalId":105852,"journal":{"name":"Proceedings of the 2019 International Conference on Robotics, Intelligent Control and Artificial Intelligence","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122374722","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The simulation results showed that the stress distribution was in a dynamic change process during elliptical vibration turning. Compared with conventional cutting, EVT technology can increase the shear angle, and the chip formed in the EVT process was thinner and had larger bending degree.
