In order to suppress many strong disturbances while aero-engine is working at steady-state, Auto Disturbance Rejection Control (ADRC) for aero-engine rotor speed was studied in this paper. By analyzing characteristics of the controlled object and making full use of Smith predictor, the two-order Smith-ADRC Controller instead of directly using three-order controller was designed which could avoid the shortcoming of tuning a large number of parameters and effectively compensate time delay of the controlled object. The simulation results show that the designed two-order Smith-ADRC controller can effectively suppress instantaneous and random disturbance, and can be suitable for aero-engine control.
