An electrically powered suspension system includes: an electromagnetic actuator that is provided between a vehicle body and a wheel of a vehicle and generates a load for damping vibration of the vehicle body; an information acquisition part that acquires information on a state of a road surface ahead of the vehicle; a target load calculation part that calculates a target load for preview control based on the road surface state, and a load control part that performs load control on the electromagnetic actuator. The target load calculation part estimates an actual input timing based on the vehicle speed and calculates an adjustment start timing related to suspension characteristics, based on the estimated actual input timing. When estimating the actual input timing based on the vehicle speed, the target load calculation part applies, to the vehicle speed, a correction coefficient for correcting a fluctuation of the vehicle speed.
