| 摘 要： | 针对如何改善静止变流器输出电压波形质量、减小开关损耗等问题,提出一种基于改进遗传算法(ImprovedGenetic Algorithm,IGA)的PID控制策略,该方法可在全局空间内对PID参数进行寻优,并能迅速收敛到全局最优解。设计以三相ZVZCT软开关逆变器为主功率变换器、DSP芯片TMS320LF2407为主处理单元的静止变流器实现方案,并制作调试了一台600 VA原理样机。实验结果表明,基于改进遗传算法的PID数字控制软开关静止变流器,变换效率高,开关损耗低,输出电压波形好。

| Abstract: | A form of PID control strategy based on improved genetic algorithm was proposed to improve the output voltage quality and reduce the loss of switching.The excellent PID parameter can be searched in global roomage by this strategy and the global optimal solution can be rapidly converged.A blueprint of static inverter,which used DSP chip TMS320LF2407 as its main disposal unit and the three-phase ZVZCT inverter as its main power transformation unit was designed.A 600 VA principle sample was built and debugged.... |
