METHOD FOR FAULT IDENTIFYING IN NONLINEAR SYSTEMS
Abstract. The problem of estimating the magnitude of faults in nonlinear dynamic systems in the presence of external disturbances is solved. The solution uses optimal control methods based on the transformation of the original system to a reduced linear system of a special type, sensitive to faults and insensitive to disturbances. Unlike sliding observers, traditionally used to solve this problem, the proposed approach allows avoiding high-frequency switching.
