An active fault tolerant controller is designed for the attitude control of a faulty spacecraft.
Feedback linearization and Lyapunov’s direct method are used to solve angular velocity
equations and to ensure convergence of the system outputs to reference inputs, respectively.
In order to ensure finite time convergence, final time constraints are proposed. Three con-
structive objective functions are considered as performance measures and optimized using
multi-objective optimization. The results show that the outputs converge to the reference
attitudes, even for severe actuator faults/failures.
