PG-PL型调速器动态过程的数值分析

Number Value Analysis of the Dynamic Course of the PG-PN Governor

针对美国伍德华特(Woodward)公司生产的PG PL型调速器,先建立其动态方程,再进行动态数值分析.对微分数 学方程,没有采用传统的拉普拉斯变换的方式,而是直接采用将微分形式简化成一维差分的形式,然后再进行迭代计算,将 方程组的计算过程就视为调速器的动态过程.通过对动态方程各参数的优化计算,推导出一组合理的参数,并将每个参数对 调节过程动态特性的影响进行了分析.论文结果对调速器的设计与数值仿真具有意义.

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.
