Research on a Servo control system for Flow Regulation

Aiming at the problem of engine flameout caused by higher or lower air-fuel ratio, an electric servo system for engine gas flow regulation is designed. In view of the situation of large instantaneous load and short-term locked rotor that the servo system may encounter in the process of flow regulation, the control software is designed with various protection measures, and the incomplete differential PID control method is adopted to improve the system's anti-interference ability. The simulation results indicate that the system has the advantages of small volume, high output torque, fast response and good stability.
