实现逆变器mpc控制的功能，模型由本人自己搭建，可供交流学习，严禁用于商业用途(Realize the function of MPC control of inverters. The model is built by myself. It can be used for AC learning. It is strictly forbidden to be used for commercial purposes.)

VB6.0在窗口中实现背景渐变，渐变可随窗口的大小变化自动填充，挺平滑的渐变，修改渐变可修改VB中的代码即可，本渐变不仅限于窗体背景，也可用于其它的窗口元素中，比如按钮和对话框中。

本文论述了在控制的一个重要方面电网连接的电源转换器，即检测基波正序分量的电网电压不平衡和扭曲的条件下。明确地,提出了一种积极的基于一种新的序列检测器双同步坐标系的解耦锁相环（双dq–PLL），完全消除了检测误差传统的同步参考框架（SRF–锁相环PLL）。(This paper deals with an important aspect in the control of grid connected power converters, that is, detecting the fundamental positive sequence components of the grid under unbalanced and distorted voltage conditions. Clearly, a positive decoupling PLL a new sequence detector based on dual synchronous coordinate system (double DQ - PLL), the complete elimination of the traditional synchronous reference frame detection error (SRF - PLL PLL).)
