Practical Stability of a Class of Switched Nonlinear Positive Systems

The practical stability problem of a type of switched nonlinear positive systems (SNPSs) with external disturbance under average dwell time (ADT) switching signal is addressed in this thesis. The adequate conditions for the practical stability of each solution of the system are obtained. In contrast to other papers, external disturbance which is bounded is taken into account in this paper and the result incorporates the previous conclusions. Moreover, compared to other papers the nonlinear functions are restricted to a sector field. Eventually, a numerical instance is adduced to prove the validity of the conclusion.
