摘要: 为研究模糊控制与变增益控制的关系，提出了一个非线性变增益模糊PID（proportion，integration，differentiation）控制方法．该方法的隶属度函数是一个可调节隶属度函数，此函数更加具有普遍性，可调节范围广．将此隶属度函数应用于模糊控制的理论中，能够增加控制器的可调性．对该函数连续性进行了证明．将该控制方法应用于仿真以及半实物实验平台，实验结果进一步说明了该函数的可行性．Abstract: To study the relationship between fuzzy control and variable gain control,a method of nonlinear fuzzy PID(proportion,integration,differentiation) control is proposed.The method's membership function has a wide adjustable range and is universal.The application of this function to the fuzzy control increases controller adjustability.The continuity of the function to also proved.This method is applied in simulation and semi-physical experiments to prove its feasibility.
