论文摘要
提出了一种新的策略来控制通过活动整流器连接的直流微电网中的内部永久磁铁发生器。控制器设计基于使用单数扰动理论将系统动力学分解为慢速和快速模式的分解。内部电流控制器是基于输出调节技术开发的,并使用非线性模型预测控制(NMPC)提出了外电压控制器。 NMPC调节DC总线电压并最大程度地减少AC侧损耗。然后根据飞机电力系统的现实条件提出仿真结果。
A new strategy is proposed to control interior permanent magnet generators in dc microgrids interfaced through an active rectifier. The controller design is based on the decomposition of the system dynamics into slow and fast modes using singular perturbation theory. An inner current controller is developed based on output regulation techniques and an outer voltage controller is proposed using Nonlinear Model Predictive Control (NMPC). The NMPC regulates the dc bus voltage and minimizes the ac side losses. Simulation results are then presented based on realistic conditions for aircraft power systems.
