ACTUATOR DRIVE CONTROL METHOD FOR ACTIVE VIBRATION CONTROLLING SUPPORT SYSTEM

摘要

PROBLEM TO BE SOLVED: To enable arbitrary setting of waveform of a lift amount of an actuator, while preventing increase in power consumption and the heat generation at a driver of the actuator of an active vibration controlling support system.;SOLUTION: In each of continuous and a lot of minute time regions, voltage to be applied to the actuator is duty controlled, so that the waveform of the lift amount of the actuator can be arbitrarily set. By varying the number of the continuous minute time regions constituting a fixed pattern in change of a duty ratio, a period of the lift amount of the actuator can be arbitrarily set. Since electrical energy and heat energy are not consumed worthlessly in the driver of the actuator, the heat generation at the driver and increase in power consumption are prevented.;COPYRIGHT: (C)2002,JPO
