Abstract

This paper proposes a memory space adjustable repetitive controller (RC) for an unfolding-type isolated Cuk inverter operating in the continuous conduction mode (CCM). To achieve acceptable tracking performance with reduced computation burden and memory space, we use the memory space adjustable RC in addition to the proportional-integral (PI) controller and the feedforward controller. Two right-half plane (RHP) zeros in the transfer function of the Cuk CCM inverter cause phase lag of the closed-loop control system. To compensate for the phase lag accurately under the low-sampled environment, we develop a fractional-order phase-lead compensator in the memory space adjustable RC. Simulation and experimental tests using a 300-W unfolding-type Cuk CCM inverter have verified the proposed controller achieves desirable performance.
