Abstract

The paper deals with the problem of integrated fault estimation and fault tolerant control for constrained linear systems with bounded external disturbances. In particular, the above coupling causes that control and estimation influence each other. Thus, to prevent an unacceptable performance of the entire system, a new integration strategy is proposed, The proposed framework is based on an output feedback framework that consists of two stages: off-line – a low-complexity LMI-based optimization task and on-line – a deterministic model predictive control problem. The proposed approach is assessed using a cascade two-tank system example.
