我们现利用卡尔曼滤波估计其位移和速度。 设位移z=x1,速度v=x2,由运动学方程可以建立状态空间方程: 设该观测传感器受随机干扰v(k)影响,可得其方程: 也就是我们的卡尔曼状态空间方程: 代码如下: function main clc;clear; T=1; N=800/T;%采样周期和采样次数 X=zeros(2,N); X(:,1)=[95;1]; Z=ze...

Data Types: double | single filter(b,a,x,zi,dim):dim是指定维度,如果x是一个矩阵,那么如果dim为1(默认值),那么就把对矩阵的每个列进行滤波,如果dim为2,则对矩阵的行进行滤波。 Filter Data in Sections Use initial and final conditions for filter delays to filter data in sections, especially i...
What Is Filter Design in MATLAB? Digital filters are central to almost every signal processing system. Filters eliminate unwanted artifacts from signals to enhance their quality and prepare them for further processing. Digital filters are used in a variety of signal processing tasks including outlier ...
