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.
