  "textContent": "An electrically powered suspension system includes: an electromagnetic actuator generating a driving force for vibration damping of the vehicle; an information acquisition part acquiring information on a stroke velocity of the electromagnetic actuator; a damping force calculator calculating a target damping force of the electromagnetic actuator, based on the information on the stroke velocity acquired by the information acquisition part; and a drive controller based on the target damping force calculated. The damping force calculator performs frequency-shaping of the stroke velocity for suppressing a low-frequency component of the stroke velocity, calculates an adjusted damping force based on the information on the stroke velocity after the frequency-shaping, and adjusts the target damping force using the adjusted damping force calculated. The suspension system appropriately suppresses vibration near a system resonance point while keeping excellent ride quality of the vehicle.",
