摘要
混流式水轮机调节系统是一个强非线性系统。对此,本文将模糊控制与常规PID控制手段结合起来,提出了混流式水轮机调节系统采用双模控制方法。充分利用了模糊控制和PID控制的优点,系统得到了较高的控制精度和稳定性。同时,还建立了基于MATLAB/SIMULINK的系统仿真。通过仿真试验证明:基于双模控制控制策略的混流式水轮机调节系统模型是可行的。
Aimed at non-linear characteristic of the Francis turbine governing system, the author brought forward a controller which combine the FUZZY control with the enormously PID control. This form a new double model controller of the Francis turbine governing system. The controller improves dynamic and static. At the same time the system simulation model is built with MATLAB/ SIMULINK. The simulation results verify that the model is feasible.
