The predictive control of single-phase UPS system for fast dynamic characteristic

Research on ADRC controller design for three‐phase UPS with multi‐disturbances

“…In [5], deadbeat dynamic response of controlled variables in uninterruptible power supply is realised by using predictive controller and error observer. Reference [6] uses predictive control method to reduce the dynamic response time of the system when UPS conducts mode transfer and overcomes the shortcoming of poor dynamic performance of traditional proportional integral (PI) controller. Reference [7] proposes a control structure that is based on the parallel interconnection of a filtered repetitive controller and a resonant controller applied to UPS, in which the filter in series with the repetitive controller adjusts the phase angle between resonant and repetitive loops, improving the tracking performance.…”
