| Abstract: | Digital valve control servo system is studied in this paper.In order to solve the system problems of poor control precision and slow response time, a CMAC-PID( cerebellar model articulation control-ler-PID) compound control method is proposed.This compound controller consists of two compo-nents:one is a traditional PID for the feedback control to guarantee stability of the system;the other is the CMAC control algorithm to form a feed-forward control for achieving high control precision and short response time of the controlled plant.Then the CMAC-PID compound control method is used in the digital valve control servo system to improve its control performance.Through simulation and ex-periment, the proposed CMAC-PID compound control method is superior to the traditional PID con-trol for enhancing stability and robustness, and thus this compound control can be used as a new control strategy for the digital valve control servo system. |
