ROBUST EXPONENTIAL STABILIZATION FOR VEHICLE ACTIVE SUSPENSION SYSTEMS WITH AN INPUT DELAY

针对具有输入时滞及控制量和输出约束的汽车主动悬架不确定系统,研究了鲁棒H_∞指数镇定问题.通过设计状态反馈控制器,使得闭环系统鲁棒指数稳定,并且能够有效地抑制外界干扰.通过实例仿真验证了所设计控制器的有效性和可行性.

Aiming at vehicle active suspension systems with a input delay and the input and output constraints, robust H∞ exponential control problem is studied. A state-feedback controller is designed to guarantee that the resulted close-loop system is robust exponential stable, and disturbance can be attenuated. The simulation results of a real example verify the effectiveness and feasibility of the method proposed.
