%X A novel non-smooth observer is proposed to handle the state estimation for sandwich systems with hysteresis. Based on the characteristic of the system, a non-smooth state-space model is proposed by using the separation principle. A non-smooth observer is developed based on the state-space model. The observer is switched among different operating zones automatically according to the operating conditions. The convergence of the non-smooth observer is discussed. Simulation results are presented. The comparison between the proposed non-smooth scheme and conventional methods show that the former has better estimation performance than the others.
