Hybrid Control of Induction Motors via Sampled Closed Representations

Abstract: In this paper, a controller for induction motors is proposed. A continuous feedback is first applied to obtain a discrete-time model in closed form. Then, on the basis of these exact sampled dynamics, a discrete-time controller ensuring speed and flux modulus reference tracking is determined, making use of the sliding mode technique. The resulting controller is hence hybrid, in the sense that it contains both continuous and discretetime terms. It is shown how to implement such a hybrid controller using the so-… Show more

“…On the other hand, threephase AC machines can be classified in asynchronous, synchronous and variable reluctance machines. The asynchronous or induction motor (IM) is a popular machine widely used in industrial drive systems [3,6], due to their simple mechanical construction, low service requirements, and lower costs with respect to DC motors. Synchronous machines are classified in sinusoidal, brushless and reluctance machines, where the most popular are the sinusoidal which is characterized by a sinusoidal Back Electro-Motive Force (BEMF) and the brushless that is characterized by a trapezoidal BEMF and by using permanent magnets [23].…”
