Combined with the nonlinear characteristics of wind turbines and the control strategy of generator-side converter and grid-side converter, used the design method for digital PI regulator, the back-to-back PWM converter on the wind-power system with direct-driven permanent magnet synchronous generator was built in the simulink of the MATLAB.

结合风力机的非线性特性和机侧变换器与网侧变换器的控制策略，应用数字PI调节器参数设计方法，在MATLAB/simulink仿真环境下构建了基于背靠背变换器的永磁直驱风力发电系统，系统包括风力机、永磁同步发电机、变频器、电网及其电气控制部分的数学模型，仿真结果表明风电系统的PI调节器参数设计合理且系统具有良好的运行特性。

We met because our library carrels were back-to-back; what if we'd been assigned to opposite ends of the room?

我们相识是因为图书馆阅读隔间是背靠背的；万一要是被安排房间中对面呢？

If Sunday allows him to maintain this type of form, he could well be the only threat to Morra becoming the first-ever back-to-back tour winner.

如果周日让他保持这种类型的形式，他很可能是唯一的威胁morra成为有史以来第一次背靠背之旅的赢家。

In this dissertation, the nonlinearity of the MOS varactors caused by the large output signal of the DCO, as well as its influence on the performance of the DCO, is analyzed. A back-to-back in series digitally controlled MOS varactor is presented to avoid the nonlinearity of the varactors of the DCO.

对DCO大信号工作时所引起的数控MOS变容管的非线性以及这种非线性对DCO性能的影响进行了分析，提出了改善这种非线性的背靠背串联数控MOS变容管的新结构，可以使DCO的相位噪声最多降低8.1dB。

Jazz is 4-0 at home and 7-5 on the road in back-to-back sets. Utah plays every Friday and Saturday the rest of this month -- two at home, four roadies.

Utah will be done with its back-to-back obligations by then but there is no let-up late, since those final six games include home dates with San Antonio, Denver and Houston and roadies in New Orleans, Dallas and San Antonio.

尽管爵士终于完成了背靠背的比赛，但是他们没有喘息的机会，因为最后的6场比赛中主场要迎接马刺、掘金和火箭，而客场还要挑战黄蜂、小牛和马刺。

Having only four more back-to-back sets is a livable number compared to most teams and the Suns also have several very winnable games sprinkled in with their two remaining showdowns with San Antonio, Houston and Denver and the roadies against the Pistons and Celtics.

虽然这些要赛程让人苦恼，但他们有更大的挑战和困难要解决，那就是如何让奥尼尔这个新来的大个子赶快融入球队……纳什把这成为赛季末的&训练营&。好在只有4次背靠背的比赛，这让太阳与其他球队相比有些轻松。

A double header with Lyon will then follow ahead of a trip to Debreceni VSC.

在和里昂进行两场背靠背的重头戏之后，红军将客场挑战德布雷岑。

We have to study the situation and understand why our rivals were better than us, before tackling the double header in North America in better shape so that we can fight for the wins.

我们必须研究现在的局面并且要在接下来北美的两场背靠背比赛之前，弄清为什么对手会比我们更优秀，这样
