Title
A Reduced-Order Enhanced State Observer Control of DC-DC Buck Converter.
Abstract
This paper presents a reduced-order-enhanced state observer (RESO)-based control strategy for the PWM dc-dc buck converter. With the proposed RESO control strategy, the output voltage regulation of the dc-dc buck converter is able to achieve robust characteristics against the external disturbance and the internal parameter variation even without output current measurement. In addition, by incorporating the RESO in the controller, the output voltage regulation can be easily achieved with only a proportional gain to realize a zero steady-state error. Finally, the parameter design is discussed and the effectiveness of the proposed control strategy is verified with an experimental case study.
