输入受限不确定线性系统混合镇定
Mixed Stabilization of Uncertain Linear Systems with Input Constrains
摘要
Abstract
In view of the transient and steady performance,we propose a mixed-stability-control scheme for the uncertain linear sys-tems with input constraints.This scheme guarantees both the finite-time stability and the asymptotic stability in the sense of Lya-punov for the closed-loop system.The control problem is expressed as a feasibility counterpart of linear-matrix-inequality (LMI)con-straints.The mixed controller is a piecewise function of time,and thus potentially causes the transient j ump due to the discontinuity of the controller at the switching time.For the purpose ofretarding the vibration,this paper introduces a time-interval buffer to modify the mixed controller.Finally,the numerical simulation applied to the mathematical model of a reentry hypersonic vehicle shows the validity of the proposed approach.关键词
