基于模糊自调整PID技术的励磁控制器研究

Study on excitation controller based on fuzzy self-tuning PID technique

结合模糊控制理论和常规PID励磁控制器,提出了模糊自调整PID励磁控制技术。选取自并励励磁模型作为对象,在MATLAB软件下对常规PID励磁控制与模糊自调整PID励磁控制进行仿真研究。结果表明,模糊自调整PID励磁控制能有效地改善系统的动态品质,提高系统的抗干扰能力,对运行状态改变时模型变化的鲁棒性有较大提高。

A new scheme for fuzzy self-tuning PID excitation control technique is proposed by combining the fuzzy control theory with the normal PID excitation controller. The self-shunt exciting model is used as object. The normal and fuzzy PID excitation controllers are simulated on MATLAB software. Simulation results show that fuzzy selftuning PID excitation controller is effective.
