Modelling of microcomputer-controlled induction machine

The vector control of induction machines gives a quick response and is capable of decoupling flux and torque. An approach based on the indirect field-oriented controller is presented. The decoupling network, necessary to independently control the flux (rotor flux, airgap flux, or stator flux) and the torque of induction machines has an identical topology. An arbitrary variable can be introduced to choose between flux vectors. A digital simulation of vector control is presented, and simulation and experimental results are given
