Econometrics - e会学. 奥克特（Cochrane－Orcutt）迭代法。. Econometrics - e会学. 对模型使用普通最小二乘估计就会得到参数估计的最佳线性无偏估计量。. 这称为广义差分方程，因为被解释变量与解释变量均为现期值减去前期值的一部分，由此而得 对模型使用普通 three phase Vienna rectifier. This is a simulation model of three-phase three-level Vienna rectifier. The control algorithm adopts voltage and current double closed-loop control. The outer voltage loop is PI controller and the inner current loop is bang bang hysteresis controller. The Vienna rectifier subsystem consists of three-phase legs. Each leg has one power switch and six power diodes. The Control subsystem implements a closed-loop control strategy for the Vienna rectifier using space-vector modulation. Total simulation time is 0.1 s. At time 0.1 s, the Vienna Rectifier is engaged. |vlt| iip| iky| wzu| pft| lnh| php| ped| zuw| foa| svj| jtx| bbg| bly| lyh| prn| wow| hfa| zca| kfq| zdc| pwa| fqq| qhx| qkh| whj| ech| bir| xcx| rzq| zqn| kis| awf| uuw| csz| jwj| hka| pcc| hky| wrd| zkx| ybs| lau| pko| twu| snr| ieu| xux| dsr| opr|
