Abstract: In this paper, an electromagnetic hybrid suspension with active-semi-active hybrid control was proposed. It was arranged with three work modes, focusing respectively on improving the vibration resistance of the suspension, the grounding performance of the tire and the comprehensive performance. Combining with the advantages of active and semi-active control, an active-semi-active hybrid control system was established. A LQG control strategy was designed and the weighting coefficients of each mode were determined by genetic algorithm. Simulation analysis was carried out. The simulation results show that the electromagnetic hybrid suspension with hybrid control can significantly reduce the energy consumption compared with the electromagnetic active suspension, and its control effect is not very different from the electromagnetic active suspension. Finally, the experimental research was carried out. The experiment results are very match with the simulation results, verifying the validity of the system structure and the correctness of the control method.
