The H∞ robust control problem is resolved with 2-Riccati algorithm, and the H∞ robust controller is used in the rotating speed control of wind turbine, which results in completely wind turbine speed control within frequency band of wind speed variation.

用2-Riccati算法对H∞控制器进行求解，将该控制器用于风车的转速控制中，最终实现在风速波动频率范围内的风车完全转速控制。

A mixed sensitivity H∞ control model is constructed and the band width of wind turbine speed control is designed according to the frequency characteristic of wind speed variation and noise of rotating speed sensor. The sensitivity function is decreased within this frequency band to restrain the wind torque perturbation to wind turbine rotating speed control.

通过构造基于复合灵敏度的H∞鲁棒控制模型，根据风速的波动频率范围和传感器的噪声频率范围设计了风车转速控制的带宽，并在此带宽内降低系统的灵敏度函数，来抑制风力转矩对风车转速控制的干扰。

The traditional wind turbines using two-bladed wind rotors are being replaced with larger more modern turbines using 3 bladed rotors.

Thumb a ride: hitchhikers usually put their thumb out as cars pass by, indicating that they need a ride.

要搭顺风车的人通常伸出一个拇指表示他要搭顺风车，所以thumb a ride的意思就是搭顺风车。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
