On the Minimum Time Tracking Control of the Active Front End Converters

This article introduces the minimum time tracking control of an active front-end (AFE) converter with excellent transient performance. Since the dynamical model of the AFE converter is a bilinear system, switching control is provided for minimum time tracking with final time-varying trajectories in this system. Due to the complexity of implementing this controller, a suboptimal closed-loop controller is proposed whose dynamic performance is very close to the minimum time tracking control. Simulation and experimental results show that the suboptimal proposed controller has excellent dynamic performance against load disturbances compared with the conventional control methods.
