Abstract :
In recent years active approaches for fault detection using test signals have been developed. This paper reports on progress in extending one of these approaches from linear systems to nonlinear systems. Theoretical results are presented on the use of linearizations which is based on sufficiently small nonlinearities. An optimization based approach is also presented for large nonlinearities. Examples are given.
