Simulation of Loss Minimization Control for an Adjustable Speed Induction Motor Drive System over a Wide Frequency Range

摘要

This paper studies the Loss Minimization Control (LMC) for an adjustable speed induction motor drive sys- tem. Simulation is completed with an improved loss model of the induction motor under nonlinear conditions. Simula- tion results are given with parameters and losses of motor analysed in detail and compared with classical U/f control. Minimum loss control rules and energy saving effect are thus established for the motor.
