Exponential stability analysis for a class of switched nonlinear time-varying functional differential systems

This paper proposes a unified approach for studying global exponential stability of general class switched systems described by time-varying nonlinear functional differential equations. Some new delay-independent criteria are established this under arbitrary switching which satisfies some assumptions on the average dwell time. The obtained shown to cover and improve many previously known results, including, in particular, sufficient conditions absolute time-delay with sector nonlinearities. simple examples given illustrate proposed method.
