| Abstract: |
| The static output feedback control problem is studied for a class of discrete-time switched linear systems with polytopic uncertainties subject to actuator saturations.Based on a parameter-dependent discontinuous switched Lyapunov function and some basic lemmas,a switched robust H-infinity static output-feedback controller is designed to guarantee the locally exponential stability of the resulting closed-loop system under average dwell-time switching scheme by using a convex optimization problem subject to linear matrix inequalities(LMI) constraints.Finally,a numerical example is given to illustrate the effectiveness of the proposed design approach. |
