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. )

对数字信号进行二进制幅度调制，加载高斯噪声，然后在信号进行解调，比较解调后的信号与原始信号(Binary amplitude modulation, the digital signal to load the Gaussian noise, and then demodulates the signal, the comparison demodulation signal with the original signal)

多因子模型构建。多因子模型是量化选股中最重要的一类模型，其基本思想就是找到某些和收益率最相关的指标。并根据该指标，构建一个股票组合，期望该组合在未来的一段时间跑赢或者跑输指数。如果跑赢，则可以做多该组合，同时做空期指，赚取正向阿尔法收益；如果是跑输，则可以做多期指，融券做空该组合，赚取反向阿尔法收益。多因子模型的关键是找到因子与收益率之间的关联性。(Multi-Factor Model. Multi-factor stock selection model is to quantify the most important class of models, the basic idea is to find some of the most relevant and profitability indicators. And based on the index, to build a stock portfolio, expect the combination index outperformed or underperformed for some time in the future. If outperform, you can do more than this combination, but short of that, to earn positive alpha income if it is underperforming, you can do more than futures, short selling short the combination to earn a reverse alpha returns. Key multi-factor model is to find correlation between factors and yields.)
