BFGS算法: 可以解决无约束的最优化问题，如求目标函数的极值等。(BFGS algorithm: can solve unconstrained optimization problems, such as seeking the extreme, such as the objective function.)

针对频率周期振荡的振动系统讨论自适应控制问题,在频率跟踪的基础上对频率变化的振动响应进行控 制,给出相应的估计、滤波与控制方法。首先在子空间辨识原理的基础上,通过测量信号自相关序列的递推运算获得信号 频率 然后根据估计频率实时调整带通滤波器的中心频率,使其跟踪信号频率,实现信号分量的跟踪滤波 最后在LMS方 法的基础上构造对信号分量进行控制的自适应控制器。(The adaptive vibration control of systems excited by forces of periodically varying frequencieswas dis- cussed. The presented adaptive controlwas realized on the basis of tracking of time-varying frequencies and amethod for online frequency estimation, filtering and controlwas proposed. Based on the principle of subspace identification, the time-varying frequencieswere estimated from the recursively computed autocorrelation ofmeasured signals. )

说明：  MATLAB提供了多种方式从磁盘读入文件或将数据输入到工作空间，即读取数据，又叫导入数据；将工作空间的变量存储到磁盘文件中称为存写数据，又叫导出数据。(MATLAB provides a variety of ways from the disk is read into a document or data entered into the work space, that is, read data, also known as import data will work variable storage space to keep the disk file is called to write data, also known as export data .)
