摘要

摘要: 分析了三相脉冲宽度调制(Pulse width modulation, PWM)功率因数校正(Power factor correction, PFC)变换器的工作原理和数学模型. 针对现有控制方法在参数不确定及参数变化时性能变差的问题, 提出采用鲁棒变结构控制减小系统参数不确定性的影响, 同时采用渐缩滑动边界的方法减小了控制量的颤振. 仿真及实验结果表明, 与传统PI控制和反馈线性化方法相比, 本文方法不仅在标称参数时具有较好的动静态性能, 而且在系统参数发生变化时, 具有更强的鲁棒性.

Abstract: In this paper, we analyze the working principle and mathematical model of the three-phase pulse width modulation (PWM) power factor correction (PFC) converter. The performance of conventional control methods will degrade due to parameter uncertainties and parameter variations. To deal with this problem, a robust variable structure control is proposed to alleviate the performance degradation caused by parameter uncertainty; meanwhile, the time-varying boundary layer is employed to decrease the chattering of the control force. Simulation and experimental results show that, compared to traditional PI control and feedback linearization control method, the proposed method not only has nice transient and steady state performances under nominal parameters, but also has better robustness against parameter perturbations.
