  • Abstract
    The paper presents a systematic method for design of observer-controllers in cascade. Uniform global exponential stability (UGES) of the resulting system is proven by assuming that the feedback control system is UGES and that the nonlinear observer can be designed using contracting analysis. The relationship between a globally contracting and UGES observer is derived using Lyapunov analysis and a line integral which follows from Taylor´s theorem.
