Abstract:
An electrically powered suspension system includes: an electromagnetic actuator; an information acquisition unit configured to acquire time-series information related to stroke position of the electromagnetic actuator, information on stroke velocity, and an amount of change in stroke of the electromagnetic actuator and information on a stroke direction based on the time-series information; a damping force calculation unit configured to calculate target damping force based on the information on the stroke velocity; and a drive control unit configured to control driving of the electromagnetic actuator using target driving force obtained based on the target damping force. The damping force calculation unit calculates equivalent friction compensation force based on the amount of change in the stroke and the information on the stroke direction, and corrects the target damping force based on the calculated equivalent friction compensation force. The equivalent friction compensation force has elastic force component and dynamic friction force component.
