中文摘要:
这篇论文学习易于致动器浸透的交换分离时间的线性系统的柔韧的稳定问题。新交换浸透依赖者 Lyapunov 功能被利用设计一个柔韧的稳定状态最大化吸引力的领域的一个评价的反馈控制器。控制器(系数矩阵) 的设计问题然后与线性矩阵不平等(LMI ) 被归结为一个优化问题限制。一个数字例子被给显示出建议方法的有效性。
英文摘要:
This paper studies the robust stabilization problem of switched discrete-time linear systems subject to actuator saturation. New switched saturation-dependent Lyapunov functions are exploited to design a robust stabilizing state feedback controller that maximizes an estimation of the domain of attraction. The design problem of controller (coefficient matrices) is then reduced to an optimization problem with linear matrix inequality (LMI) constraints. A numerical example is given to show the effectiveness of the proposed method.
