摘　　要：针对采用PI双闭环控制策略的三相六开关有源功率因数校正(APFC),在遭受到外界干扰或者工作状态发生改变时振荡幅度大、恢复时间长、自适应能力差等问题,提出了一种基于动态滑模控制的双闭环控制器的实现方法,以满足对负载突变的快速响应和提高对系统参数改变时的强适应性。使用Matlab工具搭建了仿真模型,通过与传统的PI双闭环控制策略对比来验证所提出控制方法的优越性。最后,利用实验结果进一步验证了所提出的控制策略的正确性和有效性。For the three-phase six-switch APFC adopting the PI double closed-loop control strategy,when the external interference or the working state changes,the oscillation amplitude is large,the recovery time is long,and the adaptive ability is poor.A double closed-loop controller based on dynamic sliding mode control was proposed,which could meet the rapid response to sudden load changes and improve the adaptability to changes in system parameters.A simulation model was built by Matlab tool.The advantages of the proposed control method were verified by comparing with the traditional PI double closed-loop control strategy.Finally,the experimental results further verify the correctness and effectiveness of the proposed control strategy.
