摘　　要：同步发电机带脉冲负载系统中,脉冲负载的周期性突变会导致机端电压的波动,为此本文提出了一种模糊PID控制励磁电压的策略。该策略通过控制励磁电压从而对机端电压进行控制,能够有效避免机端电压波动较大的问题,并提高系统的响应速度和可靠性。基于MATLAB/Simulink进行了建模仿真,仿真结果与预期相符,验证了控制策略的可行性。In the system of synchronous generator with pulse load,the periodic mutation of pulse load will lead to the fluctuation of terminal voltage.This paper proposes a strategy of fuzzy PID to control the excitation voltage.The strategy controls the terminal voltage by controlling the excitation voltage,which can effectively avoid the problem of large fluctuation of terminal voltage and improve the response speed and reliability of the system.The modeling and simulation are established based on the MATLAB/Simulink.Simulation result is consistent with the expectation,which verifies the feasibility of the fuzzy PID strategy.
