emd
- 该方法的关键是经验模式分解，它能使复杂信号分解为有限个本征模函数（Intrinsic Mode Function，简称IMF），所分解出来的各IMF分量包含了原信号的不同时间尺度的局部特征信号。经验模态分解法能使非平稳数据进行平稳化处理，然后进行希尔伯特变换获得时频谱图，得到有物理意义的频率。与短时傅立叶变换、小波分解等方法相比，这种方法是直观的、直接的、后验的和自适应的，因为基函数是由数据本身所分解得到。由于分解是基于信号序列时间尺度

滑模变结构控制MATLAB仿真(第2版)仿真程序
- 滑模变结构控制本质上是一类特殊的非线性控制，其非线性表现为控制的不连续性，这种控制策略与其它控制的不同之处在于系统的“结构”并不固定，而是可以在动态过程中根据系统当前的状态(如偏差及其各阶导数等)有目的地不断变化，迫使系统按照预定“滑动模态”的状态轨迹运动。由于滑动模态可以进行设计且与对象参数及扰动无关，这就使得变结构控制具有快速响应、对参数变化及扰动不灵敏、无需系统在线辩识， 物理实现简单等优点。该方法的缺点在于当状态轨迹到达滑模面后
