Abstract :
According to the two-stage digital electro-hydraulic servo valve developed by us, a digital electro-hydraulic servo system of speed governor system of turbine was built. The detailed work principle of this system was described in this paper. Then the parameters of this system were designed base on the actual demand. And the mathematical models of this system were built. The controller of the system uses the traditional PID control method. Finally we take simulation study on it. The simulation results of the mathematical models demonstrate that the system has good dynamic properties and is suitable to the application of project.
