A new multiple-model indirect adaptive actuator failure compensation control scheme is developed, in order to achieve faster and more accurate compensation of failure uncertainties. For each possible failure pattern, a controller is designed using the direct model reference adaptive actuator failure compensation control method. A multiple-model control switching mechanism is set up by finding the minimal performance index to select the most appropriate control law. The performance index is based on the adaptive estimation errors of adaptive control design. Simulation results from an aircraft flight control system example are presented to show the desired closed-loop system stability and tracking performance despite the presence of uncertain actuator failures.
