摘要
本文主要研究不间断电源(UPS)的控制设计,对不间断电源的电路拓扑进行理论分析,在传统双环控制基础上引入了电压平均值外环,设计一种三环控制的UPS系统,建立系统的传递函数,计算PI参数,并在MATLAB中搭建仿真模型,验证模型及参数的正确性,同时与实验结果相比较。结果表明传递函数计算出的PI值对实际应用具有参考作用,三环控制的UPS系统输出波形质量提升。
This paper mainly studies the control design of uninterruptible power supply(UPS),analyzes the circuit topology of UPS theoretically,and introduces the voltage average value outer loop on the basis of traditional double-loop control.A three-loop controlled UPS system is designed,the transfer function of the system is established,the PI parameters are calculated,and the simulation model is built in MATLAB to verify the correctness of the model and parameters.Then the experimental results are compared.The results show that the PI value calculated by the transfer function has a reference role for practical application,and the output waveform quality of the three-loop controlled UPS system is improved.
