Examples
- After identifying the parameters , because of the multiplication terms of state variables , the induction motor model is still the non - linear state equations . to estimate the state variables of motor model and gain the rotor flux and velocity signals , the paper proposes a method to estimate them using extended kalman filter
在电机参数进行辨识以后，电机状态方程由于存在状态变量的乘积项，仍然是非线性方程，为了对电机状态方程进行状态估计，得到电机的转子磁链和转速信号，本文采用扩展卡尔曼滤波进行状态估计。 - Relative to general ar model , the setar model was more suitable to describe the price movement during the manipulation . to help the practice of the guarding system , the author try to set up a discrimination model for insider trading and market manipulation , based on the samples of daily - average return and turn - over ratio during the time the equity changed . the criterion is to try to correctly find out the offense and the normal event
除了日均换手率之外的日均内容摘要收益率、日均收益率平方项、日均收益率与日均换手率的乘积项能提高对内幕交易、市场操纵的发生以及非内幕交易、非市场操纵事件的正确判别率，这些变量对内幕交易、市场操纵的判别影响不一样，并且，内幕交易和市场操纵判别模型中的最优阀值也不一样，最优阀值的选取可以体现监管层监管水平的成熟程度。
