Abstract :
The purpose of this paper is to design a moving horizon observer for mode and continuous state estimation of nonlinear switched systems. Using the past output measurements and the model equations, mode and continuous state estimation is expressed as an optimization problem which is solved using the Gauss-Newton algorithm. The performances of this method are illustrated on a simulated two-tank system.
