在周期性的内燃机曲轴瞬时转速实测信号中常会出现许多畸点。为滤除畸点 ,一般采用低通滤波的方法。但低通滤波法有其局限和不足之处 ,为此 ,提出了一种快速衰减畸点值而不会带来其他误差的方法
In the periodic engine crankshaft instantaneous speed measured signal often appear many distortions. To filter the distortions, the general low-pass filtering method. However, the low-pass filtering method has its limitations and shortcomings. For this reason, a method of rapidly attenuating the value of anomalous point without any other error is proposed
