Abstract :
The paper is devoted to the problem of fault isolation in technical systems described by nonlinear dynamic models containing non-smooth nonlinearities. So-called “model-free” or “data-driven” method is used to solve the problem. The feature of this method is that parameters of the system under consideration may be unknown. The algebra of functions is used to solve the problem under consideration.
