Abstract:

In order to drive the existing induction motors efficiently, the energy loss should be minimized during its operation. It has been reported that the analytically designed optimal torque and the rotating speed trajectories minimize the energy loss of the induction motor (IM) drive system under given drive conditions. In the reported analytical methods, however, the iron loss and other un-modeled loss are neglected. Hence, the numerical design methodology has been proposed in order to derive the optimal trajectories minimizing the energy loss based on the loss map. The loss map is experimentally measured from the electrical input and the mechanical output power for various motor torque and rotating speed. However, derived optimal trajectories may cause sudden acceleration and deceleration. As a result, big jerk appears. Moreover, the trajectories of the rotor flu should be taken into account for energy saving. On these stand points, this paper proposes a numerical design methodology of the optimal trajectories of IM drive system based on the 3-dimensional loss map composed by motor torque, rotating speed and rotor flu in order to reduce loss energy and suppress the jerk. The effectiveness of the proposed method will be illustrated by means of some experiments.
