摘要
主要探讨了模糊PID在非线性、时滞控制系统中的应用 ,提出了混合PID的控制算法 ,并在MATLAB上进行仿真对比实验 ,结果发现 ,对于给定的被控对象 ,传统PID与混合PID都能取得良好的控制效果 ,但当被控对象结构参数发生变化后 ,传统PID控制性能明显变差 ,甚至发散 ,而混合PID仍能取得良好的控制效果 。
The paper discusses the application of fuzzy PID in non linear and time delay system, proposes an algorithm of hybrid PID and makes tests with MATLAB It is found that both the traditional PID and hybrid PID can get good results for given controlled objects,but when the form and parameters of controlled objects are changed, the controlling property of traditional PID becomes weak, even unstable; however, the hybrid PID remains to be effective, indicating its strong robustness.
