Passive fault tolerant control of piecewise affine systems with reference tracking and input constraints

A passive fault tolerant controller (PFTC) based on state feedback is proposed for discrete-time piecewise affine (PWA) systems. The controller is tolerant against actuator faults and is able to track the reference signal while the control inputs are bounded. The PFTC problem is transformed into feasibility of a set of linear matrix inequalities (LMIs). The method is applied on a large-scale live-stock ventilation model.
