Proposal of a new phase compensation method for LMS adaptive control

Abstract

These years, as we require the comfort at the time of boarding, it is proposed Active control engine mounts which is the equipment for automobile vibration suppression. For the ACM system, Filtered-x LMS adaptive control method which has a simple structure, is used. In this method, the transfer model that changes controller's output voltage into ACM's thrust, is needed. So, the model error is generated and system's instability is caused. In this paper, I would like to propose a method of determining the net parameters for the new LMS adaptive control algorithm which does not have to get the transfer model in advance.
