提出了一种新的不确定离散时间系统的广义 H2／H∞混合控制综合方法，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。考虑车辆前、后轴侧偏刚度参数的不确定性，利用该方法设计底盘集成控制策略，协调控制主动前轮转向系统和主动悬架系统。基于 Matlab／Simulink 与 Carsim 联合仿真平台进行典型工况仿真分析。结果表明，设计的车辆底盘集成广义H2／H∞混合控制器能够明显地改善车辆的行驶方向稳定性和防侧翻能力。

A novel method to develop a generalized mixed H2 /H∞ control for uncertain discrete-time system was proposed,and it was transformed into a convex optimal problem with constraints of linear matrix inequalities with less conservative.Considering the uncertain parameters of cornering stiffness of vehicle front and rear axle,by using this proposed method,the vehicle chassis integrated control strategy was proposed to coordinate the active front wheel steering system and active suspension sys-tem.Based on Matlab/Simulink and Carsim platform typical cases were simulated.Simulation results show that the generalized mixed H2 /H∞ controller for the vehicle chassis integrated system can signifi-cantly improve the stability of the traveling direction and anti-rollover capability of the vehicle.
