永磁同步电机模糊PID控制器的研究

摘要

In this paper, a brief introduction to the basic theory of fuzzy control and functions of PID control is given and the mathematical modeling of the permanent magnet synchronous motor is carried on. The transfer function of the mathematical model of permanent magnet synchronous motor is obtained by reasoning that will provide a theoretical basis for building the block diagram of the simulation later. Through a series of parameter adjustment, a set of optimal parameters are found to meet the requirement of the no - difference speed control. The simulation results of the fuzzy PID controller are compared with those of the conventional PID controller and the case without controller to demonstrate the advantages of the fuzzy PID controller.%对模糊控制的基本理论和PID控制的功能作出简单的介绍,对永磁同步电机进行数学建模.通过推理得到永磁同步电机数学模型的传递函数,为后面建立仿真框图提供理论依据.通过一系列参数的调整,找到一组最优的参数,达到对转速无差控制的目的,并且与常规的PID以及毫无控制器时的仿真图作出充分的对比,体现了模糊PID控制器的优越性.
