英文摘要

      An adaptive CMAC controller for hydraulic turbine governor is discussed. The adaptive CMAC controller has a two dimensional memory area, the horizontal memory location is selected by the speed of the hydraulic turbine and the vertical memory location is selected by the speed error between the turbine speed and the input signal. All of these two dimensions are linearly coded. The first order learning law and the conception of generalization is used to update the memories of the CMAC. A reference model and the direct adaptive law are employed to obtain the on-line training signal for CMAC. In order to check the control quality of the adaptive CMAC controller, a hydraulic turbine speed governor simulation experiment system is used and an ordinary PID controller is used to compare with it. The experimental results show that the adaptive CMAC controller works well and has ability to resistant the disturbance of the system parameter change.
