A stator flux oriented vector control for induction motor drives

The present paper describes a stator flux oriented control strategy using state space controllers. The optimal determination of different controllers'parameters (suitable placement of poles, continuous adapation of coefficients to the operating point of the drive) leads to an independent control of the stator flux and the torque in different operating conditions, and consequently to good dynamic performances of the drive. The effectiveness of the proposed system is verified by computer simulation. The control implementation on a Motorola DSP 56002 is in progress.
