Expressing an observer in preferred coordinates by transforming an injective immersion into a surjective diffeomorphism

, 2018
When designing observers for nonlinear systems, the dynamics of the given system and of the designed observer are usually not expressed in the same coordinates or even have states evolving in different spaces. In general, the function, denoted $\tau$ (or
