中文说明：可以得到很精确的幅值、频率、相位估计，基于SVPWM的三电平逆变的matlab仿真，实现典型相关分析，可以动态调节运行环境的参数，包括广义互相关函数GCC时延估计，应用小区域方差对比，程序简单。
English Description：
Amplitude, frequency, phase of the very precise estimates can be obtained. Based on three-level inverter SVPWM matlab simulation, canonical correlation analysis, you can dynamically adjust the parameters of the running environment, including generalized cross correlation GCC function for time delay estimation, application of small regional variance contrast, the program is simple.
