A control method for hybrid electromagnetic suspension. The method provides four modes for hybrid electromagnetic suspension: a comfort mode, a sport mode, a combined mode, and an energy feedback mode. A driver can switch between the four modes as desired. For the comfort, sport, and combined modes, hybrid control is adopted, and two sub-modes are provided: an active control mode and a semi-active control mode. A switching condition between the two sub-modes is determined by using a novel parameter Cact and comparing the same against a maximum equivalent electromagnetic damping coefficient Ceqmax of a linear motor. The present invention solves the problem of achieving a balance between suspension comfort and tire traction, and meets the demands of different operating conditions and users by enabling manual mode switching. In addition, the hybrid control is employed to solve the problems of high energy consumption of active suspension and limited control performance of semi-active suspension, thus ensuring good kinematic performance of automobile suspension while reducing energy consumption. Furthermore, the energy feedback mode is designed to enable the suspension to perform energy recovery, meeting demands of energy conservation and emission reduction.
