A field-weakening control is required in order to achieve high power output and stable control in the voltage saturation region. In this paper, a voltage phase-operated field-weakening control and a frequency-compensation control are presented. The voltage phase operation control adjusts the voltage phase command with the voltage maintained at the maximum value. Therefore the proposed control can...
This paper deals with energy optimal control of induction motor dives. When motor operate at given steady-state operation point, the optimum control efficiency is acquired by seeking the different voltage-frequency ratio so that the active power absorbed by the motor is minimization, that is improve operational efficiency and achieve the purpose of energy saving. But the minimum active power also...
