摘　　要：传统的提升机控制系统不能充分利用提升机下放重物时的势能,造成大量的能源浪费。在提升机下放重物时通过BUCK型降压变换器将发出的电储存至蓄电池可节约大量的能源。传统的BUCK型变换器多采用PI调节器,对输入侧二倍频波动的抑制能力有限。为此,提出了将重复调节器引入至BUCK型变换器的控制系统,显著提高了系统对二倍频波动的抑制能力,改善稳态时的输出电压质量。最后,在PLECS下搭建了BUCK型变换器仿真模型,仿真结果验证了控制策略的有效性。The traditional hoist control system cannot make full use of the potential energy when the hoist lowers the heavy objects,resulting in a lot of energy waste.When the heavy objects are lowered by the hoist,the generated electricity can be stored in the battery through BUCK converter to save a lot of energy.The traditional BUCK converters mostly use PI regulator,but its ability to suppress double frequency fluctuations on the input side is limited.For this reason,the repetitive regulator was introduced in the BUCK converter control system,which can significantly improve the system ability to suppress double frequency fluctuations and improve the output voltage quality in steady state.Finally,the BUCK converter simulation model was built under PLECS,the simulation results verified the effectiveness of the control strategy.
