摘　　要：针对传统的单环调压控制无法满足航空电源对系统稳态和动态的高性能要求,基于两级式无刷电励磁同步电机的高压直流电源系统,提出了改进型的输出电压加励磁电流前馈补偿双闭环控制。利用实时采样到的励磁电流变化量及其一阶导数关系式来补偿PWM输出占空比,然后结合电压调节器的反馈控制整合得到最终的输出占空比。最后,在一台6kW电励磁同步发电机上进行实验,结果表明本设计能够满足系统突加、突卸负载时的动态性能要求。In view of the traditional single loop voltage regulation control can not meet the high performance requiremerits for the steady state and dynamic performance of the air power supply, an improved double closed loop control of output voltage and excitation current feed-forward compensation is proposed based on the high voltage DC power supply system of two stage brushless excitation synchronous motor. The PWM output duty ratio is compensated by the real time sampled excitation current variation and its first derivative relation, and the final output duty ratio is integrated with the feedback control of the voltage regulator. Finally, the experiment on a 6kW electric excitation synchronous generator shows that the design can meet the dynamic performance requirements of the system when the load is loaded or unloaded suddenly.
