摘要:

针对双绕组感应电机(DWIG)交直流集成发电系统中电流环PI调节器动态响应慢、抗干扰能力不足的问题,提出一种基于扰动观测补偿电流调节器的双绕组感应发电机交直流集成发电控制策略。首先,建立DWIG交直流集成发电系统的数学模型,分析传统PI调节器在交直流耦合场景下的局限性。其次,将交流、直流电流中的耦合项总和定义为扰动项,设计扰动状态观测器,推导扰动观测值对实际值的传递函数,并给出观测器参数设计约束条件。最后,将总扰动观测值引入电流控制策略中形成前馈补偿,实现d、q轴电流以及交流、直流侧绕组电流的解耦控制。实验结果表明:所提策略有效提升了系统的电流环响应能力,改善了发电机的动态性能,并显著且有效地降低了交直流侧的相互影响,保证了交流电压与直流电压的稳定输出,为多电飞机电源系统的高性能供电提供了技术支撑。

Abstract:

To address the issues of slow dynamic response and insufficient anti-interference ability of the current loop PI regulator in the AC/DC integrated power generation system of Dual Winding Induction Motor (DWIG), a control strategy based on disturbance observation compensation current regulator for the DWIG AC-DC integrated power generation system is proposed. Firstly, a mathematical model of the DWIG AC-DC integrated power generation system is established, and the limitations of the traditional PI regulator in AC-DC coupling scenarios are analyzed. Secondly, the sum of the coupling terms in AC and DC currents is defined as a disturbance term, a disturbance state observer is designed, the transfer function of the disturbance observation value to the actual value is derived, and the design constraints of the observer parameters are given. Finally, the total disturbance observation value is introduced into the current control strategy to form feedforward compensation, realizing decoupling control of d-axis and q-axis currents as well as AC and DC side winding currents. Experimental results show that the proposed strategy effectively enhances the current loop response capability of the system, improves the dynamic performance of the generator, and significantly reduces the mutual influence of AC and DC sides. This ensures stable output of AC voltage and DC voltage, and provides technical support for high-performance power supply of more electric aircraft power systems.
