| 摘 要： | 本文提出了一种采用主动-半主动混合控制的电磁混合悬架，并且具有3种工作模式，分别侧重于改善悬架的隔振性、轮胎接地性和综合性能.结合主动控制与半主动控制的优点，建立了主动-半主动混合控制系统.设计了LQG控制策略，并通过遗传算法确定了各模式下的加权系数.进行了仿真分析，结果表明：采用混合控制的电磁混合悬架相比电磁主动悬架，能够明显减少能量消耗，且控制效果与电磁主动悬架相差不大.最后进行了试验研究，试验结果与仿真结果较为一致，从而验证了电磁混合悬架系统结构的有效性和控制方法的正确性.

| 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. |
