Abstract
- Among the conventional loss minimisation algorithms (LMAs), the model‐based approaches have the advantages of fast response and high accuracy. Here, a novel online model‐based power losses minimisation approach is presented for indirect field‐oriented control (IFOC) of induction motor (IM) drives. The proposed method is introduced as maximum torque per power losses (MTPPL) in which the power losses for a given torque are minimised. The results demonstrate that the proposed approach preserves the LMA merits, while the criterion for the MTPPL scheme is achieved. The mentioned criterion is investigated by a gradient approach so that while the gradient vectors of the torque and power losses are parallel, the MTPPL strategy is realised. The closed‐loop IFOC of the MTPPL approach is implemented in real time for a laboratory 2.2 kW three‐phase IM drive. The experimental results show the capability and validity of the proposed control scheme. [ABSTRACT FROM AUTHOR]
