Abstract
The novelty of this chapter is based on introducing a fault tolerant control FTC algorithm for collaborative subsystems which is compound of three parts; 1) designing two new optimal observers to detect and diagnose an additive fault and actuator fault in presence of disturbance, 2) constant reference output regulation control (CRC) and a new signal reference output regulation control (SRC), 3) a new intelligent reconfigured control laws for the two type of controllers to achieve the proposed control objective function. The new intelligent reconfiguration control has been developed to overcome the effects of fault or disturbance by updating the parameters of controllers. Moreover, the new interesting FTC algorithm has been applied to two subsystems that work together to achieve a common goal while the stability of the two optimal observers has been proved using the Lyapunov function. Furthermore, the proposed reconfiguration laws have been applied to eliminate the faults and disturbance according to the size of the diagnosed fault and satisfy the amount of control objective function. Finally, to test the performance of the proposed strategies, an illustrated example has been implemented and studied where the results of the simulation appear the considered performance for the FTC algorithm and the new SRC controller is more robust than the CRC controller which reflects on the improvement of the algorithm.
