Abstract: Taking the advantage of the fuzzy-neural-network's superiority in the non-linear system control,a new fuzzy CMAC (cerebellar model articulation controller) neural network model was used to control the loading system in pumping unit.The control structure and algorithm were presented.This model has been applied successfully to a passive loading system of pumping unit with the nonlinear, determinable interference and random disturbance.The simulation results demonstrate that the proposed control method is insensitive to the time-varying external disturbance and uncertainty of parameters for the system and has good generalizing property, adaptability and robustness. It is also suitable to other electricity-hydraulic servo system.
