Finite-time Control of Linear Singular Systems with Parametric Uncertainties and Disturbances
摘要
Abstract
The concept of finite-time stability for linear singular system is induced in this paper. Finite-time control problem is considered for linear singular systems with time-varying parametric uncertainties and exogenous disturbances. The disturbance satisfies a dynamical system with para- metric uncertainties. A sufficient condition is presented for robust finite-time stabilization via state feedback. The condition is translated to a feasibility problem involving restricted linear matrix in- equalities (LMIs). A detailed solving method is proposed for the restricted linear matrix inequalities. Finally, an example is given to show the validity of the results.关键词
