摘要
针对气动位置伺服系统特性随工作点位置和负载变化而变化的特点,提出采用基于Takagi-Sugeno模型(T-S模型)的模糊控制。以比例流量阀控摆动气缸位置伺服系统为例,研究了建立气动位置伺服系统的T-S型模糊控制器的一些关键技术,包括前提变量的确定、子系统的划分、模糊子集隶属函数的确定以及局部控制器的设计等。试验结果表明,采用所建T-S型模糊控制器,在较大范围内的任意负载下,执行元件行程范围内的任意位置,系统都具有良好的响应特性。
In order to make the pneumatic position servo system adaptable to the variations of the operating positions and payloads, fuzzy control based on Takagi-Sugeno model（shorted as T-S model） was proposed to be used. Taking the pneumatic rotary actuator position servo system with proportional valve as an example, the key techniques to design T-S fuzzy controller for pneumatic position servo system was studied, including the choice of the premise variables, the division of the subsystems,the definition of the membership functions of premise variables, the design of the local controllers and so on. With the developed T-S fuzzy controller, a lot of experiments had been carried out. Experimental results show that the system has better control performance for any positions within the stroke of the actuator and any payloads in a certain range.
