Filtered-X LMS 알고리즘을 적용한 능동 엔진 마운트의 진동 절연 효과

There are two seemingly contradictory requirements on engine mount:support of engine torque,and isolation of engine vibration from chassis. The first needs hard mount while the other needs soft one, but it is hard to satisfy both of them with passive engine mount. To overcome this difficulty, the active engine mount(AEM)is developed. The AEM features electro-magnetic actuator to generate secondary force so that it cancels the force transmitted to chassis by engine vibration. By examining some force cancellation schemes, the Filtered-X LMS algorithm is selected to compute the secondary vibration. This algorithm is programmed on DSP,and by experiment, it is verified that the AEM using the Filtered-X LMS adaptive controller is capable of cancelling periodic disturbance force.<br/>
