Moving Horizon Estimation and Fault Detection of Mixed Logic Dynamical Systems


D. Mignone

ETH Zuerich, Postdiploma Thesis, Automatic Control Laboratory.

A new approach for fault detection and state estimation of hybrid systems is presented. The method relies on the modeling framework for hybrid systems introduced by Bemporad and Morari, 1999. This framework considers interacting propositional logic, automata, continuous dynamics and constraints. The proposed approach is applied to the three-tank benchmark system. The fault detection and state estimation problems are formulated as mixed integer-quadratic programs and solved with branch and bound methods. For these optimizations a branch and bound tree exploring strategy is proposed, which reduces the average number of node explorations during the search of a global minimum.
