To generate a damping force by an actuator even if a unusual condition is generated in an actuator driving circuit, in regard to an active suspension for a vehicle using an electromagnetic actuator.

When the unusual condition is generated, switching operation by the actuator driving circuit 54 is stopped, and each phase coil of the actuator 12 is connected to a switch 79 through a multi-phase rectifier 78. The counter-electromotive force of each phase coil of the actuator is supplied to the switch 79, and the opening/closing of the switch 79 is duty-controlled to generate a predetermined damping force.
