Comparison of Two Repetitive Control Strategies of UPS Inverter on Saber
For the quality problem of output voltage waveform of UPS inverter, repetitive control strategy is adopted to solve the question. Analyses and comparisons of traditional repetitive control strategy and mollified repetitive control are shown in this paper. UPS inverter simulation model under two different control strategies are established on Saber simulation software platform. Simulation results show that the control effect of modified repetitive control strategy is better than that of traditional one. The output voltage can track the reference signal quickly and accurately with modified repetitive control strategy. Load disturbance and periodic error can be restrained and eliminate effectively with it.
