Abstract
In this brief, the main objective is to address the current sensorless problem of boost converter feeding unknown constant power load (CPL). A reduced-order generalised parameter estimation is first proposed to simultaneously estimate the unmeasurable current and unknown CPL of the system, which is based on dynamic regressor extension and mixing technique. Combining the estimated terms with an existing full state feedback controller, an adaptive sensorless control scheme is achieved. It is guaranteed that the closed-loop system is asymptotically stable. Finally, the effectiveness of the presented method is assessed by simulation and experimental studies.
