Anti-disturbance reference mode resilient dynamic output feedback control for turbofan systems

摘要

In this paper, the multiple disturbances reference mode tracking control problem is investigated for uncertain turbofan systems with unmeasurable states. The concerned disturbances are existing in the dynamics of turbofan systems, output measurement and control output. The control objective is described via a reference mode system, and a tracking controller is built for turbofan systems by using the reference mode control approach, disturbance observer-based-control (DOBC) scheme, resilient control technique, control theory and dynamic output feedback control method. Then, the Lyapunov stability theory and linear matrix inequalities (LMIs) technique are applied to guarantee that the augmented closed-loop tracking error systems are asymptotically stable with the performance. Finally, some simulation results for the uncertain turbofan systems are given to verify the effectiveness of the proposed method.
