Study of aeroengine multivariable robust adapting control method

This article puts forward an aeroengine multivariable robust adapting control method to solve those characteristic of areoengine: high non-linear and uncertain model. The method based on the principle of CGT robust adapting control, combines the rectified rule of parameter adapting with the robust item based on σ correction, avoids the design of mutivariable decoupling controller, and improves the robustness of the aeroengine control system. A robust adapting control system for turbofan engine stable state is constructed and simulated over dynamic process. The simulation data shows that: the system has good decoupling characteristic and adaptive ability in whole flight envelope. Thus, a practice method is provided for robust adapting research of aeroengine control system.
