对于一个含有明显噪声的心电信号进行卡尔曼滤波处理，最大程度地 “还原”信号，达到去除噪声的目的。卡尔曼滤波（看成维纳滤波的一种实现方法）的特点如下： a) 是根据上一状态的估计值X(n-1)和当前状态的观测值Z(n)推出当前状态的估计值X(n)的滤波方法,不需要用过去的全部观测值。 b) 它是用状态方程和递推方法进行估计的，因而卡尔曼滤波对信号的平稳性和时不变性不做要求。 c) 使用全部观测值保证平稳性。(Kalman in matlab,if you need it,please download it.)

在风力发电的模拟系统中,风速模拟是一个重要的环节,正确的风速模型不仅能够很好的 反应实际风速变化情况,而且能够给风力发电系统研究提供正确的源参数。本文用 Matlab/Simulink建立了风速组合数学模型,该模型将风速分为基本风速、阵风、渐变风速和噪声风 速4部分,仿真结果表明该模型能够理想的反应实际风速 (Wind speed simulation is an important part in the simulation of wind power generation system, wind speed model can well reflect the actual wind speed changes, but also to provide the correct source parameters to the wind power system studies. Wind speed combination of mathematical model using Matlab/Simulink, the model will be divided into basic wind speed, gust, gradient, wind speed and noise wind wind simulation results show that the model can be the ideal response to the actual wind)
