Abstract

This chapter proposes a control strategy consisting of adaptive control and H_∞ technique for three-phase two-level ac/dc power converters. Cascaded two loop control structure in VOC mode is adopted. For outer voltage regulation loop, an efficient adaptive controller is designed to regulate dc-link output voltage to its reference in the presence of external disturbances. For inner current tracking loop, two H_∞ controllers are designed in dq SRF to force the grid currents to track their reference values generated from the outer loop. The effectiveness and advantage of proposed strategy is verified through simulation, using sliding mode control as comparison baseline.
