(一) PMSM 的数学模型 交流电机是一个非线性、强耦合的多变量系统。永磁同步电机的三相绕组分布在定子上，永磁体安装在转子上。在永磁同步电机运行过程中，定子与转子始终处于相对运动状态，永磁体与绕组，绕组与绕组之间相互影响，电磁关系十分复杂，再加上磁路饱和等非线性因素，要建立永磁同步电机精确的数学模型是很困难的。为了简化永磁同步电机的数学模型，我们通常做如下假设： 1) 忽略电机的磁路饱和，认为磁路是线性的； 2) 不考虑涡流和磁滞损耗； 3) 当定子绕组加上三相对称正弦电流时，气隙中只产生正弦分布的 磁势，忽略气隙中的高次谐波； 4) 驱动开关管和续流二极管为理想元件； 5) 忽略齿槽、换向过程和电枢反应等影响。 永磁同步电机的数学模型由电压方程、磁链方程、转矩方程和机械运动方程组成，在两相旋转坐标系下的数学模型如下： (l)电机在两相旋转坐标系中的电压方程如下式所示: d d s d d c q q q s q q c d di u R i L dt di u R i L dt ωψωψ?=+-????=++?? 其中，Rs 为定子电阻；ud 、uq 分别为d 、q 轴上的两相电压；id 、iq 分别为d 、q 轴上对应的两相电流；Ld 、Lq 分别为直轴电感和交轴电感；ωc 为电角速度；ψd 、ψq 分别为直轴磁链和交轴磁链。 若要获得三相静止坐标系下的电压方程，则需做两相同步旋转坐标系到三相静止坐标系的变换，如下式所示。 cos sin 22cos()sin()3322cos()sin()33a d b q c u u u u u θθθπθπθπθπ?? ?-????? ??=--- ? ???? ???? ?+-+? ?

Unit 10 第4课时（Section B 2c-Self Check）测试卷 测试时间：20分钟 I.阅读理解 In the eyes of many foreigners, Chinese are the best hosts (主人) and the worst guests in the world. They’re not really bad guests, but because the guest-host relationship in China is much different than in some western countries, it appears they are not nice guests. And western hosts sometimes look rude (粗鲁的) in the eyes of Chinese guests. In China, guests are almost like gods. Whenever I enter a Chinese person’s home, there is always fruit on the table for me, and someone is quick to bring me a cup of tea or water. In the west, generally the guest is not a god. Acting according to the host’s way of doing things is usual behavior for a guest. My wife’s mother, a very kind elderly Chinese lady, doesn’t smoke. When I see some of her guests smoking in her house, as a non-smoker, I feel unhappy. Usually I want to stop them directly, but I must realize that in China, to be a good host, she must not do that. In most North American homes, if you are a guest, and the hosts are not smokers, you should not smoke in their house. At the very least, you could ask, “Is it OK if I smoke?” But, don’t be surprised if they say, “No, you can’t smoke.” In our culture, if you smoke in their home, you are a bad gue st, but if they do not allow you to smoke in their house, they are not a rude host. Guests in China also have special habits. Some western people may not adapt to these habits very soon. Thankfully my wife is Chinese, so whenever we visit a Chinese family she tells me to buy them a gift. However, giving a gift to a host is not always necessary in my country. So, if you invite international guests to your house, don’t be too surprised if they don’t bring you a gift. In China, you probably won’t need to chang e the guest-host relationship very much because you will probably only be the host, and Chinese are naturally very good hosts. If western hosts invite you to their house, try not to be too surprised if their style of treating you is not what you have expected. 1. Many foreigners think that Chinese hosts are the _________ in the world. A. best B. worst C. most natural D. most different 2. When a western guest visits a Chinese family, he often _________. A. buys some fruit B. feels like a god C. wants some gifts D. takes a cup of tea 3. If the writer’s guests want to smoke in his house, what will he probably say? A. It’s OK if you smoke here. B. Let’s smoke together. C. Sorry, you can’t smoke here. D. Smoking is a bad habit. 4. Wha t is the meaning of the underlined phrase “adapt to” in the passage? A. think back to B. get used to C. look forward to D. keep close to 5. What is the main idea of this passage? A. Foreigners should learn from Chinese. B. Hosts must do thin gs in the guests’ way. C. Western hosts are always nice to guests. D. People should understand cultural differences. II.书面表达 践行文明礼仪从我做起。作为一名学生，我们应该不断提升文明素养，做文明礼仪的倡导者。请以Be a student with good manners为题，写一篇短文。内容必须包括以下要点：
