变速恒频电源闭环控制系统的设计与仿真

The Design and Simulation about the Closed-Loop Control Technology of VSCF Power System

提出了一种小功率变速恒频电源系统的设计方法。在此系统中交流发电机使用永磁同步电机,交直交变换器采用PID加重复的控制策略。这种设计可以明显地减小系统的体积和重量。通过仿真分析可知,电源系统输出电压的频率和幅值恒定,精度高,畸变小。

A new design method of the low power VSCF power system is presented in this paper. In the system, a permanent magnet machine is used as AC generator, PID and repetitive strategy is used to control the AC-DC-AC converters. It could make the power system smaller and lighter. Through the computer simulation analysis, we know that the outputvoltage has constant frequency and amplitude with high precision and low distortion.
