  • robust output feedback stabilization of axial flow Compressors with uncertain compressor characteristics
    Conference on Decision and Control, 2012
    Co-Authors: Tiantian Jiang
    Abstract:

    In this paper we develop a semiglobal robust output feedback controller for rotating stall and surge in axial flow Compressors with certain kind of compressor characteristic uncertainties. The controller is designed by combining the backstepping control and the extended state observer (ESO). It is proven that the maximum pressure rise equilibrium can be robustly stabilized in the sense that the trajectory of closed loop system can arbitrarily close to the equilibrium after a finite time. The feasibility and effectiveness of the proposed method are further illustrated by simulating an example of a axial flow compressor with an uncertain compressor characteristic.

  • Brief Rotating stall control for axial flow Compressors
    Automatica, 2001
    Co-Authors: Calin Belta, Andrew G. Sparks, Siva S. Banda
    Abstract:

    Rotating stall is a primary constraint for the performance of axial flow Compressors. This paper establishes a necessary and sufficient condition for a feedback controller to locally stabilize the critical equilibrium of the uniform flow at the inception of rotating stall. The explicit condition obtained in this paper provides an effective synthesis tool for rotating stall control.

  • an overview of rotating stall and surge control for axial flow Compressors
    IEEE Transactions on Control Systems and Technology, 1999
    Co-Authors: Andrew G. Sparks, Siva S. Banda
    Abstract:

    Modeling and control for axial flow compression systems have received great attention in recent years. The objectives are to suppress rotating stall and surge, to extend the stable operating range of the compressor system, and to enlarge domains of attraction of stable equilibria using feedback control methods. The success of this research field will significantly improve compressor performance and thus future aeroengine performance. This paper surveys the research literature and summarizes the major developments in this active research field, focusing on the modeling and control perspectives to rotating stall and surge for axial flow Compressors.

  • Bifurcation based nonlinear feedback control for rotating stall in axial flow Compressors
    International Journal of Control, 1997
    Co-Authors: Andrew G. Sparks, Siva S. Banda
    Abstract:

    Classical bifurcation analysis for nonlinear dynamics is used to derive a nonlinear feedback control law that eliminates the hysteresis loop associated with rotating stall, and extends the stable operating range in axial flow Compressors. The proposed control system employs pressure rise as output measurement and throttle position as the actuating signal for which both sensor and actuator exist in the current configuration of axial flow Compressors. Thus, our results provide a practical solution to rotating stall control for axial flow Compressors.

  • Rotating stall control for axial flow Compressors
    Proceedings of the 37th IEEE Conference on Decision and Control (Cat. No.98CH36171), 1
    Co-Authors: Calin Belta, Andrew G. Sparks, Siva S. Banda
    Abstract:

    Rotating stall is a primary constraint for the performance of axial flow Compressors. This paper establishes a necessary and sufficient condition for a quadratic feedback controller to locally stabilize the critical equilibrium of the uniform flow at the inception of rotating stall. The explicit condition obtained in this paper provides an effective synthesis tool for rotating stall control.

  • Robust stabilization of axial flow Compressors with uncertain pressure-flow maps
    IEEE Transactions on Control Systems Technology, 2000
    Co-Authors: Alexander Leonessa, Vijaysekhar Chellaboina, Wassim M. Haddad
    Abstract:

    We develop globally robustly stabilizing controllers for rotating stall and surge in multimode axial flow compressor models with uncertain pressure-flow compressor performance characteristic maps. Specifically, using Lyapunov stability theory, a switching nonlinear globally robustly stabilizing control law based on equilibria-dependent Lyapunov functions with converging domains of attraction is developed. The locus of the equilibrium points on which the equilibria-dependent Lyapunov functions are predicated is characterized by the axisymmetric stable pressure-flow equilibrium branch of the nominal compression system. The proposed robust nonlinear control framework is directly applicable to uncertain compression systems with actuator amplitude and rate saturation constraints while providing a guaranteed domain of attraction. An application to a two-mode axial flow compressor with an uncertain pressure-flow map and rate saturation control constraints is presented.
