Each combination of values represents the current position of the BLDCM rotor. When the rotor position changes, the sensor level will change and the MCU will be interrupted. According to the position code, the corresponding power tube is opened or closed to drive the BLDCM. Changing the duty cycle of PWM can control the conduction time of power tube to adjust the BLDCM speed. If the voltage temperature and speed sampling signals exceed the allowed range, the PWM signal will be blocked to protect the controller and the BLDCM.","PeriodicalId":11066,"journal":{"name":"DEStech Transactions on Computer Science and Engineering","volume":"45 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74576080","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}

EM algorithm is an effective method to realize maximum likelihood estimation, which is mainly used for parameter estimation of incomplete data. It greatly simplifies the likelihood function equation by assuming the existence of latent variable, while maximum likelihood estimation is a commonly used parameter estimation method, and the EM algorithm makes its application more extensive. This paper takes clustering algorithm as the main research object, introduces the basic idea of maximum likelihood estimation, describes the basic theory of EM algorithm, and realizes EM algorithm. The experimental results show that compared with the traditional clustering algorithm, the EM algorithm has better convergence and clustering ability.","PeriodicalId":11066,"journal":{"name":"DEStech Transactions on Computer Science and Engineering","volume":"30 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76694357","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}
