SVPWM based on the realization of the permanent magnet synchronous motor simulation, simulation results than traditional direct torque control torque ripple small, fast response, good robustness.

詳細說明：實現(xiàn)了基于SVPWM的永磁同步電機仿真无码av永久免费专区调教，仿真結果比傳統(tǒng)直接轉(zhuǎn)矩控制轉(zhuǎn)矩脈動小，響應快，魯棒性好毛色黄片。

Due to hexagon flux control or six-section circle-flux used in traditional direct torque control,it is easy to form large torque ripple twelve section control method of voltage select table and the implementation was presented.

由于傳統(tǒng)的直接轉(zhuǎn)矩控制采用六邊形磁鏈控制或六區(qū)間的圓形磁鏈控制欧美a网站，容易造成轉(zhuǎn)矩脈動大。

The induction motor stator-flux-oriented vector control scheme not only reduces the big dependence of its performances on the rotor parameters, such as in the rotor-flux-oriented vector control, but also eliminates the torque ripple produced by Bang-Bang control in Direct Torque Control. So the SFO vector control is a high-performance and robust induction motor control scheme.

異步電機按定子磁場定向的矢量控制克服了按轉(zhuǎn)子磁場定向的矢量控制系統(tǒng)對轉(zhuǎn)子參數(shù)的依賴性人人摸人人操91制片，又沒有直接轉(zhuǎn)矩控制中的砰—砰控制帶來的轉(zhuǎn)矩脈動国产美女丝袜喷水，是一種魯棒性良好的高性能異步電機控制策略。

The vibrations can be effectively suppressed under various operation modes, including chopping control and single pulse control, by adopting the novel control strategy. Furthermore, the novel control strategy minimizes the torque ripple under the torque chopping control.

采用新的控制策略AAA国产精品久久久免费，在斬波控制和單脈沖控制下国产综合精品一区二区，振動都可得到有效抑止，且新控制策略可在轉(zhuǎn)矩斬波控制下減小轉(zhuǎn)矩脈動美女扒开腿高潮喷水网站。

This invention concerns a current control process for a feed-in voltage converter, wherein a detected flux-inducing current component and a detected torque-inducing currrent component of an actual currrent vector of a rotating field machine are each controlled for a flux-inducing current component set value and a torque-inducing current component set value of the rotating field machine. To that effect, a control set-value (DELTA u*sp, DELTA u*sq) is determined, dependent each time upon a determined current component control deviation. From these, current components of an actual current vector are formed each time by overlay of a formed pilot value (u*spvor, u*sqvor). This invention also concerns a device for carrying out this process.
