摘　　要：在分析汽车主动悬架的基本功能的基础上,将主动悬架的振动控制在数学上表述为一个凸多面体系统的多目标控制问题.鉴于系统模型中的车身质量参数可以实时测量,提出参数依赖状态反馈控制策略.将汽车主动悬架系统的鲁棒L1/H∞多目标控制器设计转化为受线性矩阵不等式约束的凸优化问题.仿真结果验证了设计方法的有效性.This paper deals with the problems of the robust multi-objective controller design for the vehicle active suspension system with the polytopic parameter uncertainty. By analyzing the basic functions of vehicle active suspensions, the vibration control for these systems is mathematically translated into a mutli-objective control problem for polytopic uncertain systems. Considering that the parameter of body mass can be measured online, we propose state-feedback control strategy via parameter-dependent Lyapunov functions. The multi-objective controller design problem is then cast into a convex optimization problem with LMI constraints. The feasibility of the methods is demonstrated by a numerical example.
