基于模糊逻辑控制交流伺服系统的研究

Study of AC Servo System Based on Fuzzy Logic Controller

论述了交流伺服系统的原理、组成、数学模型。在此模型基础上对交流伺服系统引入智能控制，对模糊逻辑控制器(FLCR)进行了深入的研究。采用FLCR能使系统克服被控对象和环境的不确定性的能力，解决了难于建模的问题，提高了交流伺服系统跟随性和抗干扰性。

This paper stated mathematical model and principle of AC s ervo system briefly.Based on it,Expert controller(ECR)-intelligent con trol of AC servo system has been studied in detail.As a result of usin g ECR this system has a ability of conquering uncertainty of controlle d object and condition.It solve the problem that hard building model i n uncertain condition.
