Abstract :
This paper develops a simple sensorless control algorithm for an induction motor. An observerless controller is proposed, which guarantees local asymptotic speed tracking-flux regulation under the condition of constant load torque. The controller development is based on the decomposition of the induction machine model in two coupled subsystems: electromechanical and electromagnetic, achieved by means of indirect field-oriented transformation. The experimental results demonstrate the steady-state and dynamic performance suitable for general industrial applications
