Abstract

This paper describes the control of automotive active engine mounts, consisting of a conventional passive hydraulic mount and an internal electromagnetic actuator. The actuator generates a force dependent on a control signal from an algorithm implemented in real time. The filtered-x least-mean-square (FXLMS) adaptive filter is applied to a system of two active mounts fitted to a saloon car equipped with a four-cylinder turbo-diesel engine. The steady state and transient performance of the active system is experimentally evaluated, and is found to typically reduce chassis vibration by 50 per cent to 90 per cent under normal driving conditions.
