Fault tolerant control is considered for a nonlinear aircraft model expressed as a linear parameter varying system. By proper parameterization of foreseeable faults, the linear parameter-varying system can include fault effects as additional varying parameters. A technique in fault effect parameter estimation reported previously (2000) allows us to assume that estimates of the fault effect parameters are available on-line. Reconfigurability (1990) is calculated for this model with respect to the loss of control effectiveness to assess the potentiality of the model to tolerate such losses prior to control design. The control design is carried out by applying a polytopic method (1995) to the aircraft model. An error bound on fault effect parameter estimation is provided, within which the Lyapunov stability of the closed-loop system is robust. Our simulation results show that as long as the fault parameter estimates are sufficiently accurate, the polytopic controller can provide satisfactory fault-tolerance.
