摘要：

This paper studies the exponential stability problem for switched systems with input saturation and parametric uncertainties. On the basis of the gain scheduling scheme (GSS) and the low gain feedback (LGF), a robust controller is constructed. The main contributions of this paper are increasing the state convergence speed of the closed-loop system by the introduced parameters and estimating the maximized region of attraction by the designed outermost ellipsoids. The corresponding conditions of the designed controller are expressed as the linear matrix inequalities (LMIs). The constructed controller is easily computed by solving the optimization problem. The numerical simulation is performed to show the feasibility and the effectiveness of the obtained results. (C) 2017 Published by Elsevier Ltd on behalf of The Franklin Institute.
