Observer linearization of nonlinear systems by generalized tansformations

Primary tabs

Guay, M.

In this paper, we study the problem of observer linearization for single output dynamical systems in the presence of an output-dependent time-scaling transformation and a simultaneous output diffeomorphism. The approach, based on an exterior calculus approach, provides a constructive approach to the problem of equivalence of a locally observable nonlinear system to a linear observer form by means of an output dependent time-scale transformation, an output diffeomorphism and a state-space diffeomorphism. A generalization of existing results is obtained which allows the treatment of a larger class of locally observable nonlinear systems.
