Prescribed performance event‐triggered control for MIMO switched nonlinear systems with unstable subsystems

This article investigates the problem of prescribed performance event‐triggered tracking control for a class of multi‐input‐multi‐output (MIMO) switched uncertain nonlinear systems, in which the solvability of the prescribed performance event‐triggered control problem for each subsystem is unnecessary. By developing a proper switching law, a prescribed performance event‐triggered low‐complexity state‐feedback control method is set up to solve the problem. Furthermore, the result above is extended to MIMO switched uncertain nonlinear systems with unavailable states by developing a prescribed performance event‐triggered low‐complexity output‐feedback control and a high‐gain observer. Also, Zeno phenomenon for the event‐triggered mechanism and the switching law is excluded. Finally, two examples verify the results obtained.
