Firstly, a reference switched system and the relative switched controller are respectively designed. Afterward, via the common Lyapunov function method, a sufficient condition that guarantees the closed-loop switched system being uniformly bounded is deduced. Finally, the proposed method is applied to control a servo-hydraulic system, the reference switched system and switched controller are given for the servo-hydraulic system on different supply pressure. Simulation results show that the desired control precision is acquired by the proposed method.","PeriodicalId":221663,"journal":{"name":"International Conference on Electronic and Mechanical Engineering and Information Technology","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116342206","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}

High level vibration and noise may lead to the control valve fully open. After analyzing the causes of vibration and noise, the noise estimation formula put forward by Masonneilan company is used to estimate noise, and two measures of pipeline modification and valve internal constitution reform are proposed. In the valve internal structure reform design, the reform is mainly focused on designing balance spool, designing and installing sleeves and limiting spool motion. The pressure experiment results show that the performance of control valve is better.","PeriodicalId":221663,"journal":{"name":"International Conference on Electronic and Mechanical Engineering and Information Technology","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126693172","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}

To adapt different measured frequencies, the position of every microphone in sound intensity probe should be adjusted. On the basis of discussing the theory of measuring sound intensity with four microphones from three dimensions, using the theory about keeping place of brace framework and parallelogram, we designed a new 3D sound intensity probe including four microphones. Because space among different microphones in sound intensity probe can be adjusted, it can choose appropriate measurement bandwidth according to the range of sound frequencies measured actually. 3D sound intensity probe with four microphones, whose measurement frequency can de adjusted, retained original advantages of 3D sound intensity probe, and overcome the shortcomings of measuring fixed bandwidth.","PeriodicalId":221663,"journal":{"name":"International Conference on Electronic and Mechanical Engineering and Information Technology","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122692963","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}
