Rotor Oriented Nonlinear Controlsystem of Induction Motors Operatingat Field Weakening

Abstract

In the presented paper, the above mentioned system is used as a solution for maximum steady-state torque production at field weakening. Forming of temporary voltage for fast reaction to dynamic changes is taken into account. The method is applied to nonlinear rotor oriented control system using nonlinear feedback. Such system insures full decoupling between mechanical and electrical variables which is very advantageous particularly at field weakening region. Real time simulation results are curried out.
