摘要
针对EAST全超导托卡马克极向场系统中极向场线圈耦合性很强,传统的方法建立的极向场系统模型非常复杂;提出了利用根轨迹法分析系统,对每个线圈单独建模,调节控制器参数使线圈对感应参数的鲁棒性足够强,实现鲁棒解耦;托卡马克放电试验结果表明,此方法整定的控制器参数,线圈电流的控制波形可以很好地跟踪预设波形,控制精度高。
In the poloidal field system in EAST （Experiment Advanced Superconductive Tokomak）, strong coupling exists among each coilo System model would be very complex if we used traditional method to design the poloidal field system. Then we model for each coil. By root locus method we tune the parameters of control system until the self inductance of each coil has excellent robust. From Tokomak test result, we can see that the tuned parameter is so good that the control system can track the setting current wave wonderfully.
