Abstract

This paper presents recent repetitive control (RP) techniques applied to uninterruptible power supplies (UPS). A proportional-derivative (PD) technique including a feedforward term is implemented as the main controller. In addition, recent repetitive control laws are presented and applied to a single phase PWM inverter. It is also presented a new RP approach for repetitive gain adaptation in the presence of cyclic and random disturbances. Results demonstrate the efficiency of each control approach.
