This paper compares several methods for computing the duty ratio which provides deadbeat output tracking for a class of PWM power convertor systems. Control computation is based on a sampled-data model and, consequently, inherently involves input nonlinearities. The comparison shows that a new piecewise-linear method is both practical and accurate.
