Abstract Aiming at the structural characteristics of the active mounting system of the vehicle powertrain and considering the influence of the dynamic characteristics of the actuator on the control accuracy of the system, a hierarchical control method is proposed. Based on the analysis of the three-degree-of-freedom (DOF) 1/4 vehicle active mounting system, the mathematical model of the mounting system and the electromagnetic actuator control circuit is derived. The upper and lower controllers are designed for the mount part and the actuator circuit part by using the layered control strategy. The upper mount controller adopts LQR control with better comprehensive performance and uses genetic algorithm to optimize its performance index weight coefficient. The lower actuator circuit adopts simple and practical PID control, besides, optimizes its parameters using particle swarm optimization algorithm. Finally, the simulation is verified by setting two typical operating conditions for the designed active mounting system. The results show that compared with traditional control, the active mounting system designed according to the hierarchical control strategy can implement more precise control for different working conditions of the vehicle, and has strong robustness and force tracking.

Key words： Electromagnetic actuator active mount LQR control genetic algorithm hierarchical control
