Abstract
This paper presents active control of electromagnetic suspension for automobiles. The authors have proposed electromagnetic damper system for automobiles for improved ride comfort and compatibility between stability and isolation. In the past studies, the proposed damper has been used as passive suspension, but in this paper, it is used as active suspension. The targets of control are to improve ride comfort and isolation of vehicle body as well as to prevent reduction of wheel toad against the input of road roughness. The newly developed electromagnetic suspension is installed in the passenger car using sliding-mode controller. It was found that the active control of the proposed electromagnetic suspension makes possible to improve the performance by computer simulations and experiments.
