Abstract :
An actuator jam failure is mitigated using a servomechanism formulation where the failed control surface is modeled as an exogenous input to the degraded plant. The approach exploits switching control, linear output regulation, H2 control theory, and an outer-loop PI control algorithm to track a desired reference input. Application is demonstrated using the nonlinear NASA AirSTAR Generic Transport Model (GTM).
