In the process of water area garbage cleaning, the cleaning equipment not only needs to avoid obstacles, but also is affected by current resistance in the process of moving. Therefore, the resistance during the moving process of the cleaning device is denoted as the potential field partial repulsion force, and the potential field function is introduced into the algorithm sampling process, so as to solve the problems of blind node expansion and slow convergence rate of RRT* algorithm itself. In addition, the fixed step size in the sampling process is changed to the dynamic step size, which makes the path obtained by RRT* algorithm smoother. Finally, the simulation based on MA TLAB verifies the feasibility and effectiveness of the improved algorithm.","PeriodicalId":202270,"journal":{"name":"2022 5th World Conference on Mechanical Engineering and Intelligent Manufacturing (WCMEIM)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122411989","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}

Stepping motor has a very bright performance in the field of automation, which has obvious propulsion effect on the formation of mechatronics system. After using the stepping motor, the error of the motor is reduced, and the positioning of the motor is more accurate. At the same time, combining the stepping motor with PLC can significantly enhance the advantages of the stepping motor. In this paper, the stepping motor based on PLC control is the main research topic. On the hardware design of the system, the design is made from the following aspects: the selection of PLC model, I/O points of input and output, the principle of automatic control and control circuit. In the software design of the system, the control program of the system is analyzed to ensure that the design requirements are met, and it has certain practical application value.","PeriodicalId":202270,"journal":{"name":"2022 5th World Conference on Mechanical Engineering and Intelligent Manufacturing (WCMEIM)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122547563","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}

However, some originally observable systems are not observable after these system transformations. For some standard normal systems with unknown interference, descriptor system form is also often constructed to design observers by using an augmented state vector. And the observability is also not always keeping in the latter transformations. The loss of observability will lead to a wrong observer, and usually it is inapparent. An extra constraint is added into the transformation matrices, and the observability can be guaranteed. Furthermore, the calculate process of the matrices is given. Two examples are shown to illustrate the correctness and the effectiveness of the presented methods.","PeriodicalId":202270,"journal":{"name":"2022 5th World Conference on Mechanical Engineering and Intelligent Manufacturing (WCMEIM)","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122619860","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}

In this study, we found the difference in the mean power spectral density (mPSD) of electroencephalography (EEG) signals between tinnitus patients and healthy people, and realized the classification of tinnitus locations by extracting the connectivity features of the brain. The feature factor with the best classification accuracy was the connectivity feature the Pearson correlation coefficient (PCC), with an accuracy of 99.42%, and the Phase locking value (PLV) also performed well.

Due to the existence of multi-source deviation and multi-point assembly of the same part in the assembly of the rotary table, the tolerance chains are more complex, and the assembly result depends on workers to correct during installation at site, resulting in low efficiency and low assembly accuracy. A three-dimensional tolerance modeling method was established based on the Jacobian-Torsor theory. A parallel assembly model was established under multi-point assembly, and the relationship between various deviation sources and assembly deviations is obtained. The contribution of each dimension chain error to the total error is obtained by Monte Carlo analysis, which provides a basis for the designer to allocate tolerance. After several times of iteration procedure, the calculated FR meets the threshold required for product assembly. This method can effectively improve the efficiency of assembly.","PeriodicalId":202270,"journal":{"name":"2022 5th World Conference on Mechanical Engineering and Intelligent Manufacturing (WCMEIM)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114879602","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}
