为了降低模糊控制器的设计难度,提高控制性能,以二维模糊控制器为基础,设计了一种具有加权因子的PID型模糊控制器,并提出了基于普通PID控制器参数整定模糊控制器参数的方法.首先,基于模糊控制器的解析结构推导,从理论上证明了该类PID型模糊控制器是一个全局二维多值继电器与一个局部具有变结构PID控制器的组合；然后,基于平衡点处该类PID型模糊控制器与普通PID控制器之间的等效关系,建立了模糊控制器系统化的参数设计方法；最后,仿真实验验证了本设计的有效性.%In order to decrease the design difficulty and improve the control performance,this paper designed a kind of PIDfuzzy controller with a weighted factor,and proposed a systematic design method of the parameters for the fuzzy controller on the basis of the conventional PID controller.Firstly,it proved the structure of the designed PID-fuzzy controller to be the combination of a global two dimensional multi-value delay and a local variable-structure PID controller.Secondly,it put forward the systematized design method for the PID-fuzzy controller on the basis of the steady state parameters of PID controller.Finally,it included the simulation results to demonstrate the effectiveness of the designed PID-fuzzy controller.
