What is the main advantage of using observer based fault tolerant controller(FTC) for sensor fault tolerance?

I am working on FTC for handling sensor faults in the system. I have read about observer-based FTC schemes which use error threshold-based logic between the states and estimated states. If a...

Can a luenberger observer (even a modified version) be effective for a nonlinear affine system?

I want to know whether a luenberger observer or a modified form of it be effective for estimating the states of a system of the following forms: 1. x_dot = f(x,u,d); y = x 2. x_dot = f(x,u); y =...
