Integrated sensor fault estimation and control for continuous-time switched systems: A new separation principle

In this paper, we address the state/fault estimation and observer-based control issues for switched systems with sensor faults. The main objective is to estimate faults compensate their effects on system state estimation, then stabilize by estimated feedback. Applying mode-dependent average dwell time (MDADT) concept Lyapunov stability theory, a new separation principle developed, which allows formalizing controller design in form of linear matrix inequalities (LMI) instead bilinear ones. Finally, highly manoeuvrable aircraft technology (HiMAT) example, DC–DC boost converter numerical example are investigated show practicability efficiency obtained results.
