Controller design and experimental validation of a power charging station for e-bike clever mobility

In this paper a suitable digital controller of a RIFT system for e-bike clever mobility is proposed and experimentally validated. Specifically, it is provided a detailed mathematical continuous-time nonlinear model of the system composed of a transformer, a bridge with characteristics of the ideal and real diodes, a filter and a battery, valid for any behavior of the supply voltage. Then, it is provided a suitable discrete-time model of the continuous model to design a digital controller. Finally, it is proposed and experimentally validated a robust discrete-time controller, which allows to charge the battery with a fixed behavior of the current.
