Abstract

The problem of simultaneous state and fault estimation for switched linear parameter varying systems with dwell-time constraint is addressed in the discrete-time domain in this paper. The polytopic dependence property is assumed for the parameter variations. By constructing a suitable dwell-time-dependent and parameter-dependent Lyapunov function, sufficient conditions to guarantee the input-to-state stability (ISS) of the augmented fault estimation error system are established to meet the ISS-gain performance requirement. Then simultaneous estimation of the states and the faults is implemented using an observer-based estimator. The applicability of the developed fault estimation method is validated by numerical results.
