In order to construct the simulation modeling of transducible vane actuator of gas turbine,the study proposes a simulation modeling method of transducible vane actuator.The simulation results show that the displacement delay of the actuator of the transducable vane in this model is consistent with the actual situation.The hydraulic cylinder piston can be well adjusted to the corresponding position according to different input signals,and accurately simulate the feed process and back process of the hydraulic regulation system,which meets the actual requirements and is feasible.
