摘要/Abstract

摘要：

基于连续时间系统的鲁棒L₂-L_∞及H_∞性能判据,推导出新的状态反馈的鲁棒L₂-L_∞/H_∞控制方法,并将其转化为具有较低保守性的线性矩阵不等式组的凸优化问题。利用该方法设计车辆底盘集成控制策略,协调控制主动前轮转向系统和主动悬架系统。采用Matlab/Simulink与Carsim联合仿真对典型工况进行验证,结果表明:所设计的车辆底盘集成L₂-L_∞/H_∞控制器在车辆极限条件下具有良好的协调控制性能,能够有效提高车辆的稳定性和防侧翻能力。

Abstract:

Based on robust L₂-L_∞/H_∞ performance criteria for continuous time system, a new approach to design robust L₂-L_∞/H_∞ controller was proposed, which was then transformed into convex optimal problem with constrains of linear matrix inequalities with low conservative. Using this method, the vehicle chassis integrated control strategy was developed to coordinate active front wheel steering system and active suspension system. Typical cases were simulated using Matlab/Simulink and Carsim. Results show that the robust L₂-L_∞/H_∞ controller for vehicle chassis integrated system has good control effect, and can significantly improve the stability of the travelling direction and anti-rollover capability of the vehicle.

Key words: vehicle engineering, robust L2-L&#x0221e, /H&#x0221e, control, integrated chassis system, active front wheel steering, active suspension system
