PID控制策略是励磁系统的主要控制方式,但当系统工况发生变化时,其不能满足系统运行的动态和稳定性要求。为克服PID控制策略的缺点,设计一种模糊PID双模控制器。仿真结果表明,基于模糊PID双模控制的同步发电机励磁控制器可以明显改善发电机在扰动条件下的动态特性,具有响应速度更快的特点,实现了励磁系统的稳定控制。

PID control strategy is the main control mode of the excitation system, but it can not meet the requirements of system stability and dynamic characteristic when the external system conditions have changed. The fuzzy-PID dual-mode controller was proposed to ameliorate the defect of conventional PID. The simulation results showed that the synchronous generator excitation controller based on fuzzy-PID dual-mode strategy could obviously improve the generator dynamic characteristics, and had the faster response action, which achieved the stability control of the excitation system.
