提出了一种具有模糊逻辑设定值加权的内模PID控制方法.该方法通过模糊系统的输出在线修正内模PID控制器比例作用部分设定值的加权系数及人工调节控制器的滤波器系数,使系统的目标值跟踪特性和干扰抑制特性均得到明显的改善.改进了常规内模PID控制的不足,而且控制算法简单、参数调整方便,理论分析和仿真试验研究结果表明了它的有效性.
An internal model PID control method with fuzzy logic setpoint weighting is proposed.The method uses the output of the fuzzy system to modify the weighted coefficient of the proportional part of the internal model PID controller and the filter coefficient of the manual adjustment controller , The target tracking and disturbance rejection characteristics of the system are obviously improved, the deficiencies of the conventional internal model PID control are improved, and the control algorithm is simple and the parameter adjustment is convenient. The theoretical analysis and simulation results show its effectiveness .
