Abstract :
This paper deals with the issue of the observer-based output-feedback of a multicellular converter. By structure, this system is not observable in the usual sense. However, under certain condition, the state vector can be available. Using finite time observer and control Lyapunov function based control, we provide an observer based strategy which satisfies the observability condition, with algebraic constraint, and stabilizes the closed loop system. Simulations on a 3-cell converter illustrate the behavior of the system under the observer based strategy.
