摘　　要：针对液位控制系统的大时滞、时变特性,提出一种基于变论域模糊控制理论的自适应模糊PID控制方法.该方法通过论域调整改善模糊PID控制器参数的调整精度和范围,具有良好的自适应能力和鲁棒性能.可以用更简单的实现方法获得比基于遗传整定的模糊免疫PID控制方法更好的控制质量.仿真结果验证了其优越性.Based on the theory of fuzzy control with variable universe, an adaptive fuzzy-PID control with universe adjusting for large-lag and time-varying liquid-level system is proposed. The solution improves the adjusting precision and range of fuzzy-PID controller through universe adjusting and has well adaptive ability and robustness. It attains better controlling quality then the fuzzy immune PID control algorithm based on genetic turning approach with easier realizing solution. The simulating results demonstrate the effectiveness of this approach.
