Study on Active Engine Mount with Electromagnetic Actuator Based on Fuzzy Control
This paper introduces an active control engine mount (ACM) designed for commercial passenger vehicles, requiring a good engine vibration isolation performance. The active engine mount is consisted of an electromagnetic actuator and an inertia-modulator hydraulic mount. The decouplers motion is controlled by the dynamic force generated by the electromagnetic actuator .The pressure in the upper chamber is variational, as a result the total output force from the mount to the chassis is controlled. Fuzzy control method was chosen as the control method. Based on force analyses of system parts, a mathematical model of the active engine mount was established. An experimental device was designed. The validity of the ACM model is experimentally verified so that it accurately predicts the dynamic behaviors of the ACM over the frequency range of interest. Finally, it is experimentally proved that the vibration isolation performance of the ACM for the engine-induced vibration of interest can be improved by more than lOdB.
