When we decimate the signal, only the sampling rate decreases but the frequency content remains same

测试不同多项式方法由卫星位置内插速度的精度。(Test different polynomial method by the accuracy of the satellite position interpolation speed.)

永磁同步电机滑膜观测器估算电机转速。精度比传统观测器精度高。(Estimation of motor speed by permanent magnet synchronous motor. The precision is higher than that of the traditional one)

用matlab编写的用遗传算法优化的神经网络的算法，读者可以根据需要进行相应参数的定义。(Prepared using matlab optimization using genetic algorithm neural network algorithm, readers can be required to carry out the corresponding definition of parameters.)

Induction machines are more rugged, compact, cheap and reliable in comparison to other machines used in similar applications. Vector controlled induction motor drive outperforms the dc motor drive because of higher transient current capability, increased speed range and lower rotor inertia

按UTM投影（或高斯投影）方式，将星下点轨迹图投影到地图坐标上 (By UTM projection (or Gaussian projection) mode, the ground track diagram projected onto the map coordinates)

计算并绘制金属材料热模拟实验加工图及失稳区域(Calculated and plotted metal thermal simulation processing maps and regional instabil)

图像的旋转，倾斜处理，以及这两个功能的合并处理(skew and rotation of image in matlab)
