Abstract
This paper proposes a novel reconfigurable control design approach for a class of nonlinear systems using a piecewise affine system approximation. The piecewise affine model is obtained in an on-line manner through linearizing the considered nonlinear system along system's real-time trajectory. The H∞ control synthesis is employed for the local reconfigurable control design. A supervisory framework is used to determine the updating of the affine system models, the reconfiguration module and the possibly nonlinear state estimation as well. The proposed method is illustrated in a ship propulsion system and the results showed the power and flexibility of the proposed method for nonlinear reconfigurable control design. The payoff of these benefits is the computation load and complexity of the reconfigured system.
