Title:
ACTUATOR DRIVE CONTROL METHOD FOR ACTIVE VIBRO-ISOLATING SUPPORT DEVICE
Document Type and Number:
Japanese Patent JP3811431
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To minimize the heating of the actuator of an active vibro-isolating support device.
SOLUTION: One cycle of the actuator for reciprocatingly moving the movable member of the active vibro-isolating support device is divided into a large number of continuous minute time zones. A voltage applied to the actuator is duty-controlled in each minute time zone, and a duty ratio at least in the last minute time zone is set to 0% to bring the current of the actuator to 0 in the final stage of one cycle reciprocating motion. Thus a current flowing when the movable member is returned to an origin at the last of the one cycle can be minimized to suppress the wasteful heating of the actuator. As a result, it can be prevented that the coil of the actuator is heated to increase the temperature thereof, the electric resistance of the coil is increased and necessary current value cannot be provided, and equipment around the coil is affected by heat.
