Modern advanced aeroengine has a wide range of work envelope. To solve the problem of supersonic aero-engine multivariable and robust control, this paper analyzes Active Disturbance Rejection Control (ADRC) controller in acceleration and deceleration process and switching afterburner state under three typical working conditions, the settling time and overshoot of ADRC control are comprehensively analyzed under the full flight envelope, the influence of the disturbance of the fan/compressor guide vane angle and the inlet ramp angle is also analyzed. The results show that the ADRC controller can realize the “zero error” following control of Nh and NPC under three typical working conditions, non-controlled parameters work in the normal range, while the NPC control loop fluctuates greatly and jumps violently under the switching afterburner state. ADRC controller can achieve stable control in the whole envelope. The response speed of NPR control loop is slightly faster than that of Nh control loop, but the overshoot is larger at high altitude, while the overshoot of Nh control loop is very small. ADRC controller can resist small disturbance of fan/compressor guide vane angle and inlet ramp angle under switching afterburner state and has good robust performance.
