经验模态分解（EMD）方法（平稳化过程）是一种全新的处理非平稳数据序列的方法，其基本思想是：假如一个原始数据序列X(t)的极大值或极小值数目比上跨零点（或下跨零点）的数目多两个（或两个以上），则该数据序列就要进行平稳化处理(Empirical Mode Decomposition (EMD) method (a smooth process) is a new deal with non-stationary data sequence method, the basic idea is: If a raw data sequence X (t) the maximum or minimum number of than the cross-zero (or under the cross-zero) number more than two (or more), then the data is necessary to carry out a smooth sequence of treatment)

说明：  该算法连续系统的抗积分饱和的PID算法,用MATlab开发，能够管直接运行,可明显减弱几分饱和现象对系统稳定性的影响，当控制量与设定值偏差较大时，取消积分作用，以免积分作用过大引起系统的稳定性降低。(The algorithm of the anti-continuous system saturated PID integral algorithm, developed using Matlab and can directly run the tube can be significantly weakened somewhat saturated phenomenon on system stability, when the control volume and settings deviation is larger, integral role in the abolition of so as not to cause too large integral role in the stability of the system lower.)
