PID controller design for a novel multi-input multi-output boost converter hub

Abstract EN

This paper reports on the design, control, and modeling of a novel multi-input multi-output boost converter topology.

The converter hub can integrate renewable energy sources such as wind turbines, photovoltaic arrays, and fuel cells for the provision of different output voltage levels.

The advantage of energy sources integration is that the required output voltage levels could be made up from a range of sources.

The designed converter has the advantages of a simple configuration, fewer components, high conversion ratio, and high efficiency.

The regulated output voltage levels are achieved through classical PID controllers which utilize the concept of closed-loop voltage-mode control.

Design of the converter control system requires comprehensive knowledge of the converter structure, its operation principle and the small-signal model for continuous-conduction operation mode.

The validity of the converter’s control performance is demonstrated through software simulation.
