Abstract :
In this paper, a method of fault estimation based on unknown input observer is presented for a class of neutral time-delay system. First, an unknown input observer is described to achieve fault estimation for neutral time-delay system with a constant delay. An observability condition is generated to guarantee observer use. Then, the observer is used to generate an algebraic method of actuator fault estimation. Finally, simulation results are presented to prove theorical development.
