IEEE 36- ROTOR ORIENTED NONLINEAR CONTROL SYSTEM OF INDUCTION MOTORS OPERATING AT 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.
