Control of induction motors by artificial neural networks

In this work, the authors propose a VSI control in open loop through the measurement of the current of the stator and using an artificial neural network (ANN). The technical control proposed has a mission to estimate the speed and torque of the rotor without necessity of using elements like tachometers or measurement of torque while the machine is working. The authors try to obtain an easy and cheap method of control with great precision and hardiness the same as other more complex schemes. The artificial neural networks receive, as inputs, the stator current and stator voltage and are trained for a collection of loads. The answers of the networks generate the estimates of the speed and the torque.
