电流型变频器实验装置关键技术研究

Research on key technology of experimental device based on current type frequency converter

自主研发电流型变频器实验装置,解决应用中的技术难点,针对其技术难点中的谐波污染和动态性能,利用能量成型控制理论设计系统控制器,实现系统的全局稳定性、无奇异点,提高系统对参数变化及外来摄动的鲁棒性,建立整流器和逆变器的互联能量成型控制新理论。

The experimental device based on the current type frequency converter is independently developed,which has solved the technical difficulties in the application.In view of the harmonic pollution and dynamic performance in its technical difficulties,the energy forming control theory is used to design the system controller in order to achieve the global stability of the system without singularity.To improve the robustness of the system to parameter changes and external perturbations,a new theory of interconnected energy forming control for the rectifier and inverter is established.
