This article focuses on the main suspension systems of current automobiles and the problems existing in active suspension systems. Firstly, the working principle of electromagnetic active suspension systems is explained, and the system design of active suspension is completed. In order to facilitate analysis, a mathematical model of active suspension is built. Then, under the same road parameters, the model is simulated and verified to verify the improvement of structural performance. Secondly, for the control strategy of vehicle stability, a PID controller is adopted, with vehicle acceleration, suspension travel, and tire dynamic load as the input objectives of the controller. The input parameters are automatically tuned and optimized using a bee colony optimization algorithm, and a mathematical expression for the optimization objective is designed. Finally, the optimal solution of the optimization objective is obtained through simulation. Through the method presented in this article, a better design and control scheme for active suspension systems can be obtained, and the practical results have strong guiding significance.
