Abstract: This controller is designed to monitor and control the specific variables while the aero-engine is running. It can perform engine protection if the signals exceed their maximum allowance. The active disturbance rejection control (ADRC) was proposed to design the limit protection controller. Advantage of the extended state observer was taken to estimate the model uncertainty and external interference of the system. The control signal was compensated through feedback. Fast protection was gotten when exceeding occurs, and safety was improved. Simulation results show that the ADRC limit protection controller can transmit the error of over limit to reference signal adjustment of the main loop very well. The overall control system responses quickly, and can carry the point of limit protection.
