Abstract

This work proposes a globally convergent state estimation method for non-linear discrete-time systems, based on interval techniques. This approach is based on a Moving Horizon State Estimation method and a global optimisation technique by interval arithmetic. This state estimation algorithm provides a solution with global convergence properties, even for non-linear model. The performances of the method are shown on a nonlinear generic biotechnological process.
