This paper presents an application of negative stiffness to carrier suspension system. The suspension is located under the center of gravity of the carrier system, which is similar to that in automobiles. In the conventional positive stiffness suspension system, the loading platform tilts to the unstable direction by inertial force during acceleration and turning. deceleration and This problem can be solved by using a suspension with negative stiffness because, the platform tilts to the stable direction, which is similar to the pendulum-type carrier. The negative stiffness is realized by zero-power magnetic suspension with disturbance feed-forward control.
