Abstract

This chapter developed a controller reconfiguration mechanism in the framework of the proposed FTC structure. The fault classification scheme used the level sets of these bounds to determine when a fault occurred for which the initial controller was incapable of compensating, and to indicate to the FMS when to switch between the nominal longitudinal controller and a degraded mode controller. This method was then applied to the longitudinal control of an automated transit bus and demonstrated in simulation for a set of both single and multiple multiplicative faults. For the controller reconfiguration, an observer-based DSC using state estimate feedback and trajectory reconfiguration was developed for intolerable faults in the sensors and actuators, respectively.
