摘 要:The doubly fed hydro-generator system is a novel type of hydraulic generation *** 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 doubly fed hydro-generator system is highly nonlinear,time-varying,large time delay and multi-variable strong *** solve this problem,a multi-variable adaptive neural network decoupling controller with PID structure is introduced based on the principle of NN control and decoupling *** decoupling and control capability of PIDNN decoupling controller are from the NN cross-tie structure and the nonlinear mapping *** weighs of the NN are learned and optimized by the particle swarm optimization(PSO) algorithm,which is known for its searching ability in the total parameter space concurrently and *** NN weights will not only eliminate the coupling relations between circuits,but also strengthen the PIDNN controller’s *** 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.
