[Abstract]
Aiming at the problem that the domestic gas turbine gas fuel control valve relies on foreign imports for a long time and lacks the ability of independent design and verification, this paper takes the actuator of the fuel control valve control system as the object, deduces and establishes its mathematical model, and uses the least squares algorithm to identify the model parameters according to the experimental data. The transfer function of the actuator of the fuel control valve control system is obtained. The dynamic response characteristics of the actuator are simulated and analyzed by using the transfer function model. The simulation results are compared with the experimental results. The overall error between the simulation and the measured results is less than 1 %, which verifies the accuracy of the established transfer function model of the actuator. Finally, the dynamic response characteristics of the fuel control valve control system are simulated and analyzed.
