A new fuzzy logic control scheme for enhanced performance: simulation and experimental studies 一种新的提高性能的模糊逻辑控制方案:仿真与实验研究

Lim","doi":"10.1006/JMCA.1994.1025","DOIUrl":"https://doi.org/10.1006/JMCA.1994.1025","url":null,"abstract":"Abstract In most fuzzy logic control schemes, the control signal is determined by using the error signal, e (.), and its first derivative, e (.), as the input signals. In this paper, these inputs signals e (.) and e (.) are modified respectively to e m (.) and e m (.), where e m (.) is given by e (.) + k m e (.) and k m is a constant. This modification enables the performance of the overall system to be further improved through a proper choice of k m . Moreover, the proposed scheme is simple and easy to implement as the number of signal to be measured remains unchanged after the modification. A non-linear power system is first chosen to demonstrate the effectiveness of the proposed scheme through simulations. The proposed scheme is specifically applied to enhance the damping of the mechanical mode oscillation of this non-linear power system. A real-time experimental study which involves the control of a servomotor is then performed.","PeriodicalId":100806,"journal":{"name":"Journal of Microcomputer Applications","volume":"94 1","pages":"369-379"},"PeriodicalIF":0.0,"publicationDate":"1994-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72939115","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}
