This paper discusses an adaptive loss minimization technique for induction motor drive systems, using an extended Kalman filter to estimate the torque and rotor speed values required to minimize the overall system loss. Additionally, the effects of parameter uncertainty on the performance of the loss minimization technique are analyzed.
this paper discusses an adaptive loss minimization technique for induction motor drive systems using extended Kalman filter. A model-based loss function is constructed first to include all major loss types in the drive system. A sensitivity analysis of the power loss model to torque and rotor flux parameters is performed. An extended Kalman filter is designed to estimate the torque and rotor speed values required for the loss function. Estimated variables are used to find the optimal rotor flux in which the overall system loss is minimized. Also, effects of parameter uncertainty on the performance of loss minimization technique are analyzed.
