Abstract:
Repetitive controller is used in a wide range of application areas; grid connected inverters,
multilink robotic manipulators, AC-DC power supplies of high precision equipment, etc. The
focus of this thesis is the performance of repetitive controller under frequency variation. A brief
introduction to repetitive controller is presented along with a review of major contributions
by well known researchers working in this area. The performance of repetitive controller is
analysed under frequency variation. Also, a number of solutions to improve its performance
under frequency variation are explored. Finally, the ndings of this thesis are validated by
applying to a Two Level Grid Connected Converter.
