Optimal Efficiency Control for Induction Motor Drives

초록

This paper presents the control algorithm for maximum efficiency drives of an induction motor system with the high dynamic performance. This system uses a simple model of the induction motor that includes equations of iron losses. The model, which only requires the parameters of induction motor, is refered to a field-oriented frame. The minimum point of the input power can be obtained at the steady state condition. The refrence torque and flux currents for the vector control of induction motors are calculated by the proposed efficiency optimization controller has been implemented by a 32 bit floating point TMS320C31 DSP chip. The results show the effectiveness of the control strategy proposed for the induction motor drive.
