abstract = {This brief studies the problem of state and fault estimation for Non-Linear (NL) systems with time delay subject to sensor fault. Additive fault tolerant control (FTC) is proposed to achieve the stability of system. The original system is transformed to linear one. The principle of fault accommodation is based on adding a new order to this nominal order. When a sensor fault affects the system, the tracking error between the reference input and the measurement deviates from zero. The nominal command then changes in order to cancel the static error and the real output therefore become different from its reference value. In the presence of a sensor defect, the objective of the accommodation is to prevent the command to evolve. This task can be accomplished by analyzing and canceling the effect of the sensor fault on the mathbfu command. After determining the amplitude of the fault, we move on to its compensation step, this step is done by adding the additive control law to the determined nominal control law. The generation of nominal control law consist to determinate the state feedback gain by using the pole placement technique. © 2022 IEEE.},
