Research of the Current Source Inverter H Robust Control Strategy

Abstract

Based on current source inverter (CSI) as the research object. In view of the three phase current source inverter control performance is influenced by load parameter variations and external disturbance problem. Put forward a H robust control strategy for the first time. Established and analysis the mathematical model of CSI model. Designed a state feedback robust H controller according to the parameter uncertainty of CSI model. Designed constant H robust controller based on the current according to system performance requirements to select the weighted function. Finally, the simulation showed the validity and feasibility of the scheme.
