Design and Implementation of Hybrid Controller and PWM Driver in a Solar-powered System

摘要：

The paper introduces design and implementation of a hybrid switching power system for an experimental low-power flyback converter in a solar-powered system. An analogue PI controller to perform precise output and control system stability is proposed and tested. An adaptive tuning digital PID regulator design example is described, with emphasis on practical limitations imposed by the LM3S1138 controller. The hybrid system combines analogue and digital systems together to adaptively adjust the regulator parameters to minimize the error between the desired performances. Experiment and simulation results of hybrid power system functionality are presented.
