Nowadays, various suspension control technologies have been developed such as active suspensions, semi-active suspensions and active stabilizers. As an alternative to a hydraulic actuator for suspension, electromagnetic devices have been developed. Electromagnetic devices are attracting much interest due to their high responsiveness, controllability, energy saving performance, and so on. Besides these advantages, electromagnetic devices can be connected to each other very easily. Therefore, the authors focus on this characteristic of the electromagnetic device and propose two methods to use coupled electromagnetic devices as an anti-rolling control device as well as vertical shock absorbers. The automobile experiences anti-rolling effects, such as roll damping and roll stabilization, without affecting the bouncing motion. Through basic experiments with two motors and control circuits, the performance of the proposed system is examined. The results indicate the coupled electromagnetic devices can be operated as a variable roll damper or a roll stabilizer. Numerical simulations of the turning automobile are carried out, and the results indicate the proposed system is effective.
