基于Matlab的加速度传感器振动信号处理方法研究

介绍了一种用Matlab信号处理工具箱进行数字滤波器设计的方法。给出了工具箱中的FDATool图形用户接口的详细使用方法,用FDATool进行滤波器设计,可以随时对比设计要求和滤波器特性调整参数,直观简便,在每次改变参数时,由于计算机的超强运算能力,只需点击设计按钮,新的滤波器立即产生,避免了传统滤波器设计的大量手工运算。并用他设计出了满足性能要求的低通数字滤波器,实现了对加速度传感器干扰振动信号的滤除,解决了工程实际问题。

Research of Acceleration Sensor Signal Processing Based on Matlab

This thesis introduces a digital filter designing method using signal processing toolbox in Matlab software.It gives detailedly using specifications of FDATool graphical user interface,when designing filter using FDATool,you can compare filter designing demand with filter character so as to adjust the parameter at any moment.For powerful operation function of the computer,when the parameters are changed,you only need point the design button,new filter will be produced.In this way,a mass of manual operation will be avoided.A good lowpass digital filter is designed using FDATool,the filter can filter preferably the acceleration sensor vibration signal and resolve the engineering problem.
