【Abstract】 This paper first establishes the dynamic equation for the Model PG-PL governor produced by the U.S.A. Woodward Company and then carries on an analysis of the dynamic number value. For the differential mathematical equation, the differential form has been adopted and simplified into the form in which one-dimensional difference divides directly instead of traditional Laplac varies, then changing and replacing calculation is made . the computational process of the equation group is regarded as the dynamic course of the governor. Through the optimization of every parameter of the dynamic equation, a group of rational parameter data is derived, and have been analyzed the influences each parameter has on the dynamic characteristic which regulate the course. The paper has certain directive significance for the design of the governor and the number value simulation.更多还原
