Робастное управление асинхронным электроприводом с минимизацией потерь мощности в реальном времени

Abstract

This paper presents a novel loss-minimizing real-time method of vector control of induction motor drive in high speed region. Proposed method determined optimal combination of stator currents, which provided loss minimization in a wide range of rotor speed, limited by current and voltage constraints. In high speed region, where those limits are reached, proposed method enable maximization of torque capability. The proposed control scheme ensures the robustness towards to changing or induction motor parameters, cross-coupling between d-q current, external impact. The validity of proposed algorithm is demonstrated by simulation.
