简单介绍一下：单相双模式逆变器、双模式控制、包含并网及独立，加上切换的仿真。滤波器上欠优化。(Brief introduction: dual-mode single-phase inverter, dual-mode control, including grid and independent, with switching simulation. Owed on the optimization of filters.)

说明：  本程序为带有偏微分的PID控制程序，很好的解决了传统PID控制的不足。(This program is the PID control with partial program, a good solution to the shortage of traditional PID control.)

Dynamic job shop scheduling problem is one form of a job shop scheduling problem with varying arrival time job or not concurrent. This problem can be represented in graph form, which is to seek the shortest path from start point to destination point. One solution that can be used is with the ant colony optimization algorithm. There are three method to input the job : xls file, matriks, and atrractive dialog.
