Direct repetitive control with gain scheduling feature for stand-alone generating applications

This paper deals with the gain scheduling feature for zero-phase-shift direct repetitive control (dRC) implemented in a FPGA system. Proposed control structure is intended to be used in ultra-low THD, fast transient response stand-alone generating applications. Moreover, implementation aspects of the dRC and gain scheduling algorithm are highlighted with reference to an industrial-grade μProcessor-FPGA control system and its graphical programming capabilities.
