摘要
本文简单介绍了基于转子加速度的起动控制的概念及其优点,并阐明了对转子加速度数据进行数字滤波的必要性,通过一阶惯性滤波和五点三次平滑两种典型的数字滤波方法对某航空发动机地面起动过程的转子加速度数据进行了数字滤波和比较分析。结果表明,采用一阶惯性滤波的方法相对适合且不会降低控制品质。
This paper introduces simply the conception and advantage based on rotor acceleration control, and expounds the necessity of digital filtering for rotor acceleration data, respectively uses the two methods of first-order inertia filtering and five-points-three- orders smoothing to do digital filtering and relatively analysis for the ground starting data of some aero-engine. The result of the calculation indicates that the method of first-order inertia filtering is fit oppositely and can not reduces controlled character.
