摘要：AbstractBoost converters are usually employed as constant or discrete variable voltage sources. They are expected as a continuously variable voltage source for electric drives (based on pulse-amplitude modulation control), or for reduction of the size of energy buffer components for mass motor drives. When changing the output voltage of boost converters according to the duty ratio, the nonlinear and nonminimum phase characteristics of boost converters cause undershoots. This study was devoted to extending the technique known as preactuated multirate feedforward (PMF), which can effectively compensate for the effects caused by nonminimum phase characteristics in boost converters. PMF was originally considered for linear time-invariant systems. In this study, the technique was extended to linear parameter-varying systems by the interpolation method. Simulation and experimental results verified the effectiveness of the proposed approach.
