Decoupling control for doubly fed hydro-generator system based on CMAC & PID

A multivariate self-adapting decoupling control method based on CMAC and PID was proposed in this paper. The control strategy utilizes PID controller and CMAC to combine a composite controller. Using the composite controller, the strong coupled time-varying system can be decoupled and controlled easily. The doubly fed hydro-generator system is a novel type of hydraulic generation system. Considering the performances of uncertain and nonlinear as well as parameters coupling and time-variation for three parts of water flux, hydro-turbine and generator, the integration of CMAC and PID control strategy is introduced. By comparison with the conventional PID control, the results of simulation show that hydro-generator system is good robustness against system parameters uncertainly and load disturbance.
