Abstract :
A control system for induction motors is introduced that keeps the generated torque equal to an arbitrarily given reference. The response of the electrical system is improved by using state feedback, where the flux value is estimated by the state observer. Then the outer alternating control inputs are adjusted to produce the desired torque. The system has very quick response. A state-space approach is used to derive the control law, which offers theoretical simplicity and the possibility of further development.<>
