In this paper, the problem of L 1 input-output finite-time control of positive switched nonlinear systems with time-varying and distributed delays is investigated. Nonlinear functions considered in this paper are located in a sector field. Firstly, the proof of the positivity of switched positive nonlinear systems with time-varying and distributed delays is given, and the concept of L 1 inputoutput finite-time stability (L 1 IO-FTS) is firstly introduced. en, by constructing multiple co-positive-type nonlinear Lyapunov functions and using the average dwell time (ADT) approach, a state feedback controller is designed and sufficient conditions are derived to guarantee the corresponding closed-loop system is L 1 IO-FTS. Such conditions can be easily solved by linear programming. Finally, a numerical example is provided to demonstrate the effectiveness of the proposed method.

“…Especially, the switched systems whose individual all subsystems are positive are called positive switched systems. The stability and FTS issues are the main matter in the field of positive switched systems, which have been extensively investigated in the literature [14,16,25,38,40,42].…”
The problem of positivity and finite-time stability for a class of discrete linear singular switched time-delay systems with mode-dependent average dwell time (MDADT) approach is investigated in this paper. New necessary and sufficient conditions for the positivity of the system are presented by employing the state-space singular value decomposition and monomial coordinate transformation methods. By establishing a novel copositive Lyapunov function and applying the MDADT switching strategy, some computable sufficient conditions are formulated to ensure the finite-time stability for a class of discrete linear singular switched positive time-delay systems in terms of algebraic linear matrix inequalities. Two numerical experiments are provided to illustrate the effectiveness and less conservativeness of the proposed results.
Representations of general solutions to three related classes of nonlinear difference equations in terms of specially chosen solutions to linear difference equations with constant coefficients are given. Our results considerably extend some results in the literature and give theoretical explanations for them.
