说明：  通过本书，读者不仅能掌握使用R及相关算法包来快速解决实际问题的方法，而且能从实际问题分析入手，到利用R进行求解，以及对挖掘结果进行分析的全面训练(Through this book, readers can not only master the method of using R and relevant algorithm packages to quickly solve practical problems, but also start from the analysis of practical problems to the comprehensive training of using R to solve problems and analyzing mining results)

本文主要内容是关于单相PWM逆变器的输出电压波形控制技术。好的输出波形 包含两个方面的要求：稳态精度高和动态响应快。本文围绕这两点，分析了重复控制 技术和双环控制技术，并进行了一系列仿真和实验。 (The output waveform correction technology of single-phase PWM inverter is studied in this dissertation.High quality waveform has two characteristics.It has not only nice static characteristic but also well dynamic response.Aiming at these characteristics, repetitive control technology and dual-loop control technology is analyzed.Both these control scheme are verified by simulation and experiment. )
