摘　　要：针对一种旋转位置控制伺服系统,提出了一种模糊变量组合的专家模糊控制方法,在MATLAB的Simulink环境下,通过S-Functions接口与数据采集卡进行数据交换,将传感器检测到的角度变量及其变化率经过模糊化,通过在线查询规则库的方式进行实时模糊推理,并通过解模糊运算给出控制信号作用于旋转伺服系统。实验结果表明,采用此策略在MATLAB环境下进行实时控制可以获得满意的效果。To implement the stable control of a rotating position control servosystem, a novel expert fuzzy control scheme which implemented on MATLAB was presented, and MATLAB communication with data sample card by S-Functions interface. At first, the angle and their changing rates were fuzzified, and then the output control signal was calculated by online searching the control tables, getting a fuzzy value after fuzzy inference and defuzzifying. Experiments verify the performance of the proposed strategy based on MATLAB, and the results prove its validity.
