Abstract

Abstract: In order to solve the problem that the traditional energy-regenerative suspension is difficult to balance the contradiction between the vibration reduction and energy-regeneration， a parallel composite electromagnetic suspension structure consisting of electromagnetic actuator and magneto-rheological damper is proposed. A model reference multi-mode switch controller is designed to improve the adaptability of parallel composite electromagnetic suspension to different road conditions， in which the characteristics of different working modes are considered， and the switching index， threshold value and corresponding control parameters are determined for the purpose of improving ride comfort. A multi-mode switching control system is designed based on Stateflow for the discrete character of switching instruction and the continuous character of state change of suspension system. The performance of model reference multi-mode switch controller are simulated and tested . The results show that the model reference multi-mode switch controller can be used to effectively implement the switching between working modes of parallel composite electromagnetic suspension， which improves its adaptability to different road conditions， and effectively balances the contradiction between vibration reduction and energy-regeneration.
