摘要：In order to come true the closed-loop control of a supersonic aircraft inlet, the dynamic identification and control of the positive shock in the inlet is studied, based on bleed air flow regulation under supersonic conditions. Using a two-dimensional CFD model of the inlet, the dynamic and static effects of bleed air flow, upstream pressure, upstream temperature and Mach number on the position of norm shock were investigated. Those transfer functions between the norm shock position and the above influent factors were identified. Based on this, an active disturbance rejection controller (ADRC) is designed for the positive shock position control in Matlab Simulink environment. The simulation results show that the designed closed-loop system has a short response time and a small overshoot, compared to conventional PI control, which can reject upstream disturbances more effectively. © 2018, Editorial Department of Journal of Propulsion Technology.
