Abstract :
In this paper we investigate the fault tolerance properties of a multisensor switching strategy previously proposed by the authors. We show that closed-loop stability of the resulting switching scheme is guaranteed in the presence of faulty sensors if a set of conditions on the system parameters (such as bounds on the sensor noises, maximum and minimum values of the reference signal, etc.) is satisfied. This constitutes an important step in enhancing and broadening the applicability of the proposed multisensor scheme since it provides guaranteed properties such as fault tolerance and robust closed-loop stability under sensor failure. The results are applied to the problem of automotive longitudinal control.
