Robust stabilization and Fault Tolerant Control for uncertain singular neutral variable time delay systems

The main goal of this work is the robust stabilization and the design of fault tolerant control to achieve the desired performance in the closed loop system. The studied system is an uncertain singular neutral variable time-delay. First, H∞ controller is developed to guarantee robust stabilization of the closed loop system. Then, an adaptive observer is designed to achieve the fault and state vector estimation. Finally, simulation results are presented to prove the theoretical development.
