摘要
本文针对水轮机调节系统的参数非线性、时变性和模型不确定性设计了一种基于模糊推理的参数自适应PID控制器,并用Matlab对该控制器的稳定性和鲁棒性进行了仿真。仿真结果表明该控制器具有理想的动态和稳态性能,超调量、过渡过程时间等控制性能指标均优于传统PID控制器,能够满足水轮机调节系统对参数控制的要求。
According to the nonlinear character and time variability of parameters and the uncertainty of model of hydraulic turbine governing system,this paper designs an adaptive PID controller of parameters based on fuzzy reasoning,and uses Matlab to simulate the stability and robustness of the controller.The simulation results show that the controller has good dynamic and steady state performance,and its overshoot,transition process time,and other control performance are better than that of traditional PID controller.It can meet the requirements of hydraulic turbine regulating system for parameter control.
