| Abstract: | Aiming at improving the working conditions of engine,an active control model for engine vibration is built based on microcomputer technique and automatic control theory.Three strategies(linear quadratic regulator control,self-tuning fuzzy control and neural network adaptive control) are adopted to effectively control engine vibration on-line with acceleration as control objective.The control effects and tracking performance of control systems are validated and the strong and weak points of different control... |
