参数在线自调整模糊控制算法研究

Arithmetic of Parameter Online Adjusting Fuzzy Control

针对间歇式热处理炉温度控制对象的特性要求,提出了参数在线自调整模糊控制与智能积分相结合的一种新型模糊控制方法。该方法的基本思想是在系统误差较大时,用参数在线自调整模糊控制算法以提高系统的响应;在系统误差较小时,加入智能积分作用以消除静态误差,智能积分作用是有选择的施加积分作用,克服了一般连续积分控制的缺点。论述了带智能积分参数在线自调整模糊控制器的设计及软件实现。并且通过在MATLAB软件上的仿真分析表明该方法的合理性及可行性。

This paper puts forward a new-style fuzzy control eter and intelligent control. During error of system is great, way by uniting fuzz）, control of online adjusting paramsystem response is enhanced by using fuzzy control of online adjusting parameter ;during error is small, system static error is eliminated by using intelligent integral control. Intelligent integral control selects useful information, conquers man）- disadvantage of common integral control. That is the new control method main idea. In this paper, there is detailed design process of this new control method and software The result of emulational experiment in MATLAB software indicate that this new control way is reasonable and feasible.
