一种确定内燃机周期信号中畸点的方法

The Algorithms Research on Distorted Point Attenuated Method

提出了一种确定周期信号中畸点的新方法,并进行了证明。此方法可在单个周期性信号中确定畸点,适用于无法用多次平均法消除畸点的周期性信号。对模拟与实测信号的应用表明,该方法能正确地确定畸点。

Numerous distorted points exist in the measuring periodic signal in internal combustion engines. A new method has been put forward and verified to be effective to testify the distorted points. The method can correctly testify the distorted points in single periodic signal. Thus it is applicable in the periodic signal which can not be eliminated by averaging method. The method is simple,applicable and easily achieved by programming. The method can correctly testify the signal by the use of simulating and measuring signal and lays the foundation for other methods.
