摘　　要：结合灰色预测、模糊自调节与传统PID控制的设计思想,提出灰色预测模糊自调节PID控制算法。该算法用系统输出误差和系统输出预测误差合成的综合误差作为PID控制器的输入,同时模糊自调节系统又能根据综合误差及其变化率来调整PID参数。仿真结果表明,与模糊自调节PID控制器相比,该控制器具有良好的动态性能和鲁棒性。Incorporating the grey prediction,fuzzy control and the conventional PID control,a design method of the grey prediction fuzzy self-regulated PID control algorithm is presented.The integrated error is made use of input of the conventional PID controller,and composed of output error and output predictive error.Fuzzy self-regulated system can adjust PID parameters according to the integrated error and its change rate.Simulation results show that this controller can achieve better dynamic performance and robustness than fuzzy self-regulated PID controller.
