摘要
针对不间断电源中所存在的未知扰动的特点,提出了将线性自抗扰控制技术应用于不间断电源逆变器电压控制器中。首先,分析了根据不间断电源逆变器电压控制器的模型,同时分析了二阶线性自抗扰控制算法的数学模型与其参数整定。其次,由于自抗扰控制技术的强干扰作用,设计了基于自抗扰的不间断电源逆变器电压控制器。最后,通过Matlab软件中的Simulink工具搭建相应模型、参数整定,完成波形调试。模型的仿真结果表明:基于二阶线性自抗扰控制的不间断电源逆变器电压控制器能够有效地抑制干扰。
Aiming at the characteristics of unknown disturbances in uninterruptible power supply（UPS）,the linear auto-disturbance rejection control technology is applied to the UPS inverter voltage controller.This paper firstly analyzes the model of the voltage controller of the UPS inverter,and the mathematical model and parameter setting of the second order linear auto-disturbance rejection control algorithm.Secondly,due to the strong interference effect of auto-disturbance rejection control technology,this paper designs an UPS inverter voltage controller based on auto-disturbance rejection.Finally,through Matlab Simulink software this paper builds the appropriate model,parameter tuning,and completes the waveform debugging.The simulation results of the model show that the UPS inverter voltage controller based on second order linear auto-disturbance rejection can effectively suppress the interference.
