Abstract :
This paper presents an observer based robust sensor fault reconstruction scheme designed by assigning right eigenvectors. It was found that if the observer had a certain eigenstructure, it could robustly reconstruct the sensor faults. The work in this paper investigates the existence conditions that guarantee a successful design. Then, it proposes an design method for the observer using Linear Matrix Inequalities, such that it is stable and has the desired eigenstructure. Design examples and simulation results validate the work in this paper; where the scheme reconstructs the sensor faults accurately independent of the disturbances.
