Comparison-of-Bayesian-and-fisher
训练错误率和交叉验证错误率相等,在样本比较大时,这个结果是可以预期的;训练错误率一般低于测试错误率,但是当样本数据比较少时,实验也出现了意外,样本多的那组测试错误率比样本少的训练错误率还要小;在本实验中,同组数据的交叉验证错误率比独立测试错误率高,这个反常现象是因为样本的原因所致,交叉验证的样本小,而独立测试时所用训练样本数目大,因而出现这种情况。分类线上,fisher准则是一条直线,而贝叶斯分类器实际上是一个类似椭圆的封闭曲线;很明显,贝叶斯分类器比fisher分类器要好。(Training error rate and cross- validation error rates are equal, the larger the sample , this result is to be expected training error rate is generally lower than the test error rate , but when comparing the sample data came from the experiment there was an accident, that more samples group test error rate less than the training sample error rate is smaller In this experiment, the same set of data cross-validation error rate than independent test error rate, this anomaly is because the sample of reasons , cross-validation sample is small,And independent testing large number of training samples used , resulting in this situation.Classification online , fisher criterion is a straight line , while the Bayesian classifier is actually a closed curve similar to elliptical It is clear that the Bayesian classifier is better than the fisher classifier .)

SVPWM_VSI
SVPWM是近年发展的一种比较新颖的控制方法,是由三相功率逆变器的六个功率开关元件组成的特定开关模式产生的脉宽调制波,能够使输出电流波形尽可能接近于理想的正弦波形。空间电压矢量PWM与传统的正弦PWM不同,它是从三相输出电压的整体效果出发,着眼于如何使电机获得理想圆形磁链轨迹。SVPWM技术与SPWM相比较,绕组电流波形的谐波成分小,使得电机转矩脉动降低,旋转磁场更逼近圆形,而且使直流母线电压的利用率有了很大提高,且更易于实现数字化。(SVPWM is a novel control method developed in recent years. It is a pulse width modulation wave generated by a specific switching mode consisting of six power switching elements of three-phase power inverters, which can make the output current waveform as close as possible to the ideal sinusoidal waveform. Space voltage vector PWM is different from traditional sinusoidal PWM. It is based on the overall effect of three-phase output voltage, focusing on how to obtain the ideal circular flux trajectory of the motor. Compared with SPWM, the harmonic component of winding current waveform is smaller, which reduces the torque ripple of motor, makes the rotating magnetic field more close to the circle, and improves the utilization ratio of DC bus voltage greatly, and makes it easier to realize digitization.)
