ABSTRACT
 This paper introduces the speed control valve’s course of development and analyzes the valve’s structure and the basic principle. Namely the way how to establish the steady-state of speed control valve and the mathematical model of dynamic mathematical model is given. The influence of the internal valve structure parameters and hydraulic parameters on the steady-state speed control valve performance and dynamic properties are got. Research related to the computer software is done and the valve’s simulation model is designed. Finally this is established by the Simulink of Matlab simulation. According to the speed control valve mathematical model establish the steady-state speed control valve model and the dynamic model with Simulink, and simulate. The results show that the theoretical analysis is correct.
 
Keywords: speed control valve; Steady-state characteristics; Dynamic characteristics;  Simulink .
