Abstract:

Using the average dwell time method, the problem of a class of uncertain switched systems with dynamic output feedback robust H∞ control is discussed. The sufficient conditions in the form of linear matrix inequalities (LMI) are presented to guarantee the stability of uncertain switched systems with dynamic output feedback robust H∞ controller under the dwell-time-dependent switching law. For optimizing disturbance attenuation performance and simplifying the solving, a dynamic output feedback controller design algorithm is given. Moreover, the result is extended to the case of an arbitrary switching law.
