This method firstly uses the least square method to identify the precise mathematical model of the system based on the input and output data of the controlled system in real time. Then, in order to reduce the difficulty of the controller parameter tuning, a method of numerically optimizing the controller parameters is proposed. We can use this method and the precise model of the system obtained in the previous step to tune the controller parameters. Through MATLAB simulation software and experimental platform, the speed control method proposed in this paper is compared with the PI control method. From the simulation and experimental results, it can be seen that the control method proposed in this paper can effectively adapt to the time-varying problem of the controlled model. After the load moment of inertia is increased by 20 times from initial value, the overshoot of the original PI control method increases at 14.8%, the adjustment time increases to 1 second. Using the control method in this paper, the overshoot can be controlled at 3% and the adjustment time can be controlled at 0.1 second.","PeriodicalId":290836,"journal":{"name":"2022 11th International Conference of Information and Communication Technology (ICTech))","volume":"2 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120918323","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 study aims to design and implement a surgical target position determination system, which is used to assist the doctor to determine the location of the surgical target in carotid endarterectomy. Based on mixed reality technology, through a novel method of matching digital virtual organ models and real physical entities, the target assisted positioning system realizes the surgical target auxiliary determination in the analysis of carotid endarterectomy process. The multiple digital three-dimensional models of ROI were visualization in mixed reality vision through the model fusion and RGBA adjustment. During the operation, the doctor aligns the digital 3D models with the physical entity in the mixed reality environment, and then determining the surgical target position through the spatial position of digital models of the carotid stenosis area. The assisted system has been implemented and verified in three carotid endarterectomy operations. To verify the feasibility and practical application value of the system, the cost time of assisted positioning process and the evaluation of doctors' used experience are counted. The results show that the clinicians could achieve intuitive visualization of surgical targets in deep spine positions with mixed reality and the target determining process of carotid endarterectomy takes a shorter time than the traditional image guided system. Conclusion is that the designed surgical target assisted positioning system makes the process of determining the surgical target of the carotid endarterectomy more intuitive. To a large extent, the method helps doctors determine the surgical target and improve the quality and efficiency in operation.","PeriodicalId":290836,"journal":{"name":"2022 11th International Conference of Information and Communication Technology (ICTech))","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115392845","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 order to identify the types of faults in rolling bearings and improve the safety of the equipment, this paper presents a fault diagnosis method on account of an improved Convolution Neural Network (CNN). The improved CNN model is to add a convolutional layer before the fully connected layer, after several convolutional layers and several pooling layers, and use an improved stochastic gradient descent training algorithm with momentum to speed up the training speed to enhance the serviceability of the model. Traditional fault diagnosis methods are time-consuming, high in labor costs and low in work efficiency. The method in this paper improves the intelligence of the rolling bearing of CNC machine tools fault diagnosis process, improves the correctness of fault diagnosis, and adapts to the characteristics of big data fault diagnosis. Finally, the data set of Case Western Reserve University's rolling bearing database is used for experimental verification. The experimental results reveal that this method has a high recognition accuracy rate for various types and severity of rolling bearing faults, and has good practicability and application prospect.","PeriodicalId":290836,"journal":{"name":"2022 11th International Conference of Information and Communication Technology (ICTech))","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128864366","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}
