摘　　要：目前大部分同步电动机励磁电源都采用相控方法,其控制存在自适应能力不高和抗干扰能力弱的问题,为此,提出了一种基于自适应神经网络模糊控制理论的PID控制的移相方法。为验证该控制方法的合理性,建立了基于该方法的励磁电源仿真模型,仿真结果表明,该方法能够弥补传统传动控制的不足,并且能够有效地解决复杂控制问题,可以动态地适应外界环境的变化,从而为同步电动机提供稳定且可靠的励磁电源,满足了实际同步电动机的工作需要。Most of the excitation power for synchronous motor is controlled through phase.The strategy has deficiencies of shorter adaptability and robustness.Therefore,phased-shifted PID control method is put forward based on Adaptive Neuro-Fuzzy theory.And simulation models are constructed to verify the plan.The results show it can availably compensate the lack of conventional control and effectively settle complicated control,and it has the excellent dynamic adaptability in various environments.So it can provide stability and security power for synchronous motor,and meets the actual needs of work for the motor.
