A Dsp-Based Active Disturbance Rejection Control Design For A 1-Kw H-Bridge Dc-Dc Power Converter, Bosheng Sun, Zhiqiang Gao

Electrical and Computer Engineering Faculty Publications

This paper presents the design and implementation of an advanced digital controller for a 1-kW H-bridge dc-dc power converter. A new control algorithm based on the active disturbance rejection concept is developed to cope with the highly nonlinear dynamics of the converter and the disturbances. An experimental digital control system is used to implement the new control strategy. It consists of a digital control board based on the TMS320C6711 digital signal processor chip, an analogy I/O board, and a complex programmable logic device pulsewidth-modulation generation board. Using a newly developed bandwidth-parametrization technique, an autotuning method based on noise quantification is …
