Suboptimal filtering for autonomous nonlinear systems.

ABSTRACT
This paper deals with the filtering problem for noisy observed non linear systems without stochastic input. A particular class of filters, each one associated with a vectorial gain and with the tipical structure containing the innovation process as forcing term, is considered. It is shown that under some suitable conditions there exists a class of non linear transformations on the state function space and a set of gain's values both depending on a positive scalar parameter, such that for small values of the parameter itself the resulting filter yields an arbitrariely small steady state error with respect the corresponding non linear trasformation. Moreover, it is shown that the steady state error is bounded for suitable value of the scalar parameter and upper bounds for both the transformed error and the "true" error are evaluated.
