Average Dwell Time Approach To H-Infinity Filter For Continuous-Time Switched Linear Parameter Varying Systems With Time-Varying Delay

Considering two types of delays including both time-varying delay and parameter varying delay in continuous switched linear parameter varying systems, the problem of H infinity filtering under average dwell time switching is illustrated. The H infinity filter depending on the linear time-varying parameter rho(t) (mode-dependent parameterized filter) is designed at first. Then, based on multiple Lyapunov function and an improved reciprocally convex inequality, the corresponding existence sufficient conditions for the filter could ensure the obtained filter error system exponentially stable with a guaranteed H infinity performance in the form of linear matrix inequalities. In addition, the designed filter gains under allowed switching signals are computed via the proposed convex optimal algorithm. In the end, two numerical examples show the effectiveness of the results in this work.
