Abstract

The problem of switching stabilization for a class of switched positive nonlinear systemsswitched positive homogeneous cooperative system SPHCS in the continuous-time context and switchedpositive homogeneous order-preserving system SPHOS in the discrete-time context is studied by usingaverage dwell time ADT approach, where the positive subsystems are possibly all unstable. To tacklethis problem, a new class of ADT switching is first defined, which is different from the previous definedADT switching in the literature. Then, the proposed ADT is designed via analyzing the weighted norm of the considered system’s state. A sufficient condition of stabilization for SPHCSs with unstablepositive subsystems is derived in continuous-time context. Furthermore, a sufficient condition for SPHOSsunder the assumption that all modes are possibly unstable is also obtained. Finally, a numerical exampleis given to demonstrate the advantages and effectiveness of our developed results.
