摘要
针对一类大时滞、时变系统,提出一种基于变论域模糊控制理论及模糊 PID 控制原理的变论域自适应模糊 PID 控制方法。该方法结合了常规模糊 PID 控制器和变论域模糊控制器各自的优点,通过论域调整改善模糊 PID 控制器参数词整精度和范围,具有良好的自适应能力和鲁棒性能。仿真结果验证了该方法的优越性。
Based on the theory of fuzzy control with variable universe and fuzzy-PID control, an adaptive fuzzy-PID controller with variable universe for a class of large-lag and time-varying system is proposed. The solution combines the advantage of both traditional fuzzy-PID controller and fuzzy controller with variable universe, improves the adjusting precision and range of fuzzy-PID controller＇ parameters through universe adjusting, and has well adaptive ability and robustness. The simulating results demonstrate the effectiveness of this approach.
