Research on high acceleration high precision air suspension control system performance evaluation algorithm

摘要

The motion performance of the high acceleration high precision air suspension platform is affected by the electromechanical characteristics of the drive system, the fluid characteristics of the air suspension guide rail and the load disturbance. The mathematical model of the system is established, and the controller performance is designed based on the optimal objective function value. The ideal controller performance is proposed as the evaluation benchmark. The performance of the system is evaluated by the ratio of the optimal objective value and the evaluation benchmark. Based on the established evaluation index, the influence of noise disturbance and estimation vector on the stability and robustness of the system is evaluated, and the system performance is further optimized.
