Abstract
These years, as we require the comfort at the time of boarding, it is proposed the active control engine mount (ACM), which is the equipment for automobile vibration suppression. For one of the ACM control methods, we use the Filtered-x least-mean-square (Filtered-x LMS) adaptive control system because of the simple structure. Before we use this control method, we need the transfer model that changes controller's output voltage into ACM's thrust. But because of time-related deterioration, the model has errors, which cause system's instability. So, in this paper, we will propose the LMS adaptive control algorithm which does not have to get the transfer model in advance.
