Abstract：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.
