This paper presents a DSP based digital control design and implementation of a high frequency dc-dc switching power supply. Starting with a dc-dc buck converter and a given set of performance specifications, different control blocks and parameters, used as in the analog control design approach, are reviewed prior to the control design in digital domain. The control loop is then analyzed and the...

A method for designing a digital robust controller for PWM power amplifier is proposed.The present controller design is based on approximate 2-degree-of-freedom digital integral-type control systems. A digital signal processor(DSP) is implemented to the digital controller obtained here. It is shown from an experiment that a sufficiently robust digital control systems are realizable.
