Abstract
A sensorless control system for an induction motor employs direct tracking of torque and flux regulation to achieve improved motor control without the need for transformation to the rotor flux related frame. A novel torqueflux dynamic model used to implement the control method employs stator voltage as an input, and achieves separation of torque and flux regulation. An alternate regulation method better suited for slow reference signals relies on a steady state solution of the dynamic model.
