摘　　要：考虑汽车转向控制中出现的微分包含系统的控制问题。首先用一非仿射不确定系统来描述这一微分包含系统，基于耗散理论分析了这一类非仿射不确定系统的鲁棒控制问题。并针对该非线性系统的有界性，给定系统鲁棒稳定的充分条件是满足一线性矩阵不等式，最后给出了一个仿真计算实例以验证算法的有效性。This paper deals with control problem for the differential inclusion system, which is needed in designing controller for active steering of vehicle. This differential inclusion system is described by a non-affine system with uncertainty. Based on the dissipation inequality, the robust control for such a non-affine uncertain system is analysed. Under the assumption of the system with a bounded nonlinear, a sufficient condition is obtained as a linear matrix inequality which guarantees the closed loop system robust stable. Finally, the simulation example demonstrates the method proposed is effective.
