Vector Controlling System with Nonlinear Model of Induction Motors

摘要

A new model based on MT synchronous rotating frame including main path saturation is developed to analysis the steady and dynamic performance of induction motor with vector controlling system. The parameters calculated by finite element analysis (FEA) guarantee the exactness of the model. The simulation results compared with those of experiment validate the model in dynamic analysis. The experiment results also show that the proper selection of rotor flux level will reduce the start-up time with higher instantaneous torque.
