Pressure Control For Oxygen Supply System Based On Adrc-Gpc

High-performance of an oxygen supply system (OSS) is essential to flight quality. But the OSS is sensible to flight conditions and pilots' breathing state, and robustness is necessary. Herein, this paper introduced the mathematical model of the OSS. Then a novel active disturbance rejection generalized predictive control (ADRC-GPC) was applied to the OSS, by combining the technique of active disturbance rejection control (ADRC) and generalized predictive control (GPC). Meanwhile, the simulation results investigated that the pressure of oxygen mask can be controlled within the limits of breathing resistance. Finally, the comparison of the simulation between GPC and ADRC-GPC showed that ADRC-GPC was more stable and more effective in lowering breathing resistance than GPC.
