Study on an Inverter with Dual-loop Control and Repetitive Control

Yong Kang

Abstract

A inverter control technology based on dual-loop control plus repetitive control is studied. The scheme added a repetitive control outer loop exccept to intorporate a current loop with an instantaneous voltage loop. After realizing output voltage decoupling and the load disturbance compensation the dual-loop controller based on deadbeat theory sends the inverter to achieve very fast dynamic response. The repetitive control outer loop improve the steady-state performance. The scheme is proved on a PWM inverter whose control system based on DSP TMS320F240.
