    摘要: An electromagnetic suspension apparatus for an automotive vehicle, employs an electromagnetic actuator interleaved between a sprung mass and an unsprung mass and arranged in parallel with a suspension spring element, and an electric motor built in the electromagnetic actuator for driving the electromagnetic actuator. A motor controller calculates a displacement input, such as a suspension stroke acceleration and a suspension velocity, transmitted to the electromagnetic actuator, and controls the motor to bring a suspension damping force closer to a desired damping force suited for the displacement input. The motor controller calculates an internal inertia force of the electromagnetic actuator, and corrects or compensates for a motor output by the internal inertia force of the electromagnetic actuator.
