摘要
This paper deals with the problem of finite-time boundedness and fin计e-time stabilization boundedness of frax?tional-order switched nonlinear systems with exogenous inputs.By constructing a simple Lyapunov-like function and using some properties of Caputo derivative,the authors obtain some new sufficient conditions for the problem via linear matrix inequalities,which can be efficiently solved by using existing convex algorithms.A constructive geometric is used to design switching laws amongst the subsystems.The obtained results are more general and useful than some existing works,and cover them as special cases,in which only linear fractional-order systems were presented.Numerical examples are provided to demonstrate the effectiveness of the proposed results.
