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 .
