Gain scheduling controller of the aero-engine based on LPV model

Throughout the entire flight envelope for aero engine within its aero-thermodynamic processes will change much, aero-engine control system is designed so that it can in any change of conditions of stable, reliable work, and give full play to your engine's performance benefits. A two-spool turbofan engine nonlinear model to represents a real engine. Depending on linearize nonlinear model to get an engine LPV model, and get the controller gain coefficients of LPV model by linear matrix inequality. Finally, the application of gain scheduling controller with nonlinear model comparing the experimental data proved that the controller reduce the response time and improve steady-state accuracy of engine HP rotor speed.
