摘要
针对模糊自整定PI控制器的不足以及永磁同步电机(PMSM)矢量控制系统的非线性、参数时变等特点,为进一步改善永磁同步电机控制系统性能,在基本二维模糊PI控制器的基础上引入了一维模糊控制器,构成了一种双模糊PI控制器。对所提出的双模糊PI控制器的输入输出关系进行理论推导并进行结构解析,得出该控制器是一种非线性的变参数PID控制器。在SIMULINK中构建系统仿真结构框图,进行仿真分析。仿真结果表明所提出的双模糊PI控制器使得PMSM具有更好的稳态性能和抗干扰性能。
The existing defects on traditional fuzzy PI controller and the characteristic like nonlinear and variable parameter of permanent magnet synchronous motor (PMSM) vector control system, in order to improve the control system performance of PMSM, based on the two-dimensional fuzzy PI controller, one dimension fuzzy controller with integral function is introduced. It is a kind of dual fuzzy PI controller. In this study, the input and output relations of the proposed dual fuzzy controller is theoretically deduced and the structure analysis is carried out. It is concluded that the controller is a nonlinear and variable parameter PID controller. The structure block diagram of system simulation is constructed in SIMULINK, and the simulation analysis is carried out. The simulation results show that the proposed dual fuzzy PI controller makes the PSMS better steady-state performance and anti-jamming performance than the traditional fuzzy PI controller.
