摘要：
It is important to realize torque and stator flux dynamic decoupling control for an induction motor drive, which is a multi-input and multi-output, nonlinear and strong coupling system. First, an integer inverse model is realized by a nonlinear state feedback system, and the effect of its inverse system precision is anlysized. Second, a stator and rotor resistance variance estimator based on the model reference adaptive system (MRAS) is designed, and an adaptive inverse decoupling control method is proposed based on stator and rotor resistance error compensation. By cascading the inverse system with the induction motor drive system, the drive system is decoupled into two independent linear loops, so that synthesis and design of linear regulators can be done separately using linear system theory. The simulation results have verified the validity of the proposed scheme. Copyright © 2010 Acta Automatica Sinica. All rights reserved.
