摘要
通过选择全程积分滑模面,设计了基于全程滑模的Boost型PFC变换器的数字控制系统。该系统可消除到达过程,实现了直流输出电压稳定以及网侧电压和电流的高功率因数控制,同时保证了系统对电路参数变化、电网波动及负载变化的鲁棒性。通过MATLAB搭建的仿真系统以及基于DSP28335的实验平台验证了该系统的正确性。
Based on selecting total integral sliding mode surface,it develops a total sliding mode control(TSMC)system for Boost type power factor correction(PFC)converter.The system can eliminate the arrival process,realizes the stability of DC output voltage as well as high power factor between the grid voltage and current control,guarantees the robustness against the variation of circuit parameters,grid fluctuations and load changes.The simulation in MATLAB and experiment on DSP28335 verify the effectiveness of the designed control system.
