摘要
This paper deals with the problem of stability analysis for a class of continuous-time switched positive T-S fuzzy systems by using mode-dependent average dwell time (MDADT) switching signals. The switched positive T-S fuzzy systems consist of both stable and unstable positive T-S fuzzy subsystems. Based on the multiple linear copositive Lyapunov function (MLCLF) and MDADT methods, a simple sufficient condition of stability for switched positive T-S fuzzy systems is first derived to guarantee the exponential stability of the systems, and the obtained condition is formulated in terms of linear programming. Finally, a numerical example is presented to demonstrate the effectiveness of the proposed method. (C) 2015 Elsevier B.V. All rights reserved.
