采用模糊控制实现的混合式同步电动机闭环控制

Closed-loop Control of Hybrid Synchronous Motor with Fuzzy Control Strategy

针对两相混合式同步电动机非线性、强耦合的特点,提出了采用模糊控制作为速度外环控制器,采用矢量控制作为电流内环控制器的结构。考虑到控制系统调节的快速性以及系统的稳态特性,提出了参数自调整的模糊控制策略。同时将仿真结果与普通模糊控制算法以及经典PID控制算法进行比较,可以看出采用参数自调整的模糊控制算法具有较好的动、静态特性。

Considering the characteristics of the nonlinearity and the strong coupling, the control structure that fuzzy control is used as the outer loop of the speed and the vector control is used as the inner loop of the current is presented. In view of the rapidity and the steady-state characteristic of the control system, the fuzzy control strategy with the self-regulating parameters is put forward. Comparing with the general fuzzy control and the PID control strategy, the better dynamic characteristic and the steady-state characteristic of the control system with self-regulating parameters can be obtained.
