Actuator drive control device for active vibration isolation support system, and methods of using same

Abstract

In an actuator drive control device for an active vibration isolation support system, amplitudes of engine vibration are estimated when a front bank and a rear bank operate. When a difference between the amplitudes is large, an operation of an actuator is controlled at the time when the front bank operates, based on the amplitude of the engine vibration at the previous time when the front bank operates, and the operation of the actuator is controlled at the time when the rear bank operates, based on the amplitude of the engine vibration at the previous time when the rear bank operates. As a result, even when the vibration state of the engine at the time of operation of each bank differs, it is possible to control the operation of the actuator based on the actual vibration state of the engine when the actuator operates, whereby engine vibration can be effectively isolated by the active vibration isolation support system.
