基于遗传算法的三相四线制逆变器优化控制的研究

建立三相四线制逆变器带不平衡负载的情况进行数学建模。在各个状态变量下对输出电流影响进行分析，得出相关的计算结果。仿真试验，列出多目标函数的表达式，在同时考虑开关损耗和电磁干扰的情况下，通过遗传算法寻找最优序列。画出最优序列下及约束条件下的波形图，并对试验结果进行比较分析，得出该算法的优越性及可靠性。

Research on Inverter's Optimization Control in Three-phase Four-wire System Based on Genetic Algorithm

Set up the mathematics model based on inverter in three-phase four-wire system with unbalance load. By analysis on influence of output current and under all kind of state variables, the corresponding calculating results are got. Considered switching loss and electromagnetism disturbance, the best list is found out by genetic algorithm. Described out the wave form under the best list and restraint condition and compared the test result, the advantage and reliability of that algorithm are educed.
