摘　　要：为解决不间断电源中整流环节对电网产生的谐波污染问题,提高网侧功率因数,基于Boost型单相功率因数校正电路,将分数阶理论、模糊控制理论与传统PID控制器相结合,应用到有源功率因数校正(APFC)系统中,使其具有更好的鲁棒性和较快的动态响应速度。在MATLAB环境下对APFC电路进行搭建,并利用Simulink库中的Fuzzy单元设计模糊控制器。通过系统仿真对控制效果进行验证,结果表明:引入模糊和分数阶控制的APFC系统具有总谐波畸变率(THD)低,动、静态性能良好等优点。In order to solve the problem of harmonic pollution caused by rectifier in the uninterruptible power supply and improve the grid-side power factor,based on Boost single-phase power factor correction circuit,fractional order theory and fuzzy control theory are combined with traditional PID controller and applies it to APFC system to make it has better robustness and faster dynamic response speed.The APFC circuit was built in MATLAB environment,and the fuzzy unit in Simulink library was used to realize the design of fuzzy controller,and then the control effect was verified by system simulation.The results show that the APFC system with fuzzy and fractional order control has the advantages of low total harmonic distortion and good dynamic and static performance.
