| Resumo: | This work proposes to perform the speed control of an induction motor (1 cv, 2 poles,
220/380 V) without the use of a mechanical sensor attached to the rotor, avoiding some
inconveniences such as a periodic maintenance and increased complexity and number of
equipment are always part of the engine running. The three phase induction motor is
the most used type of machine for electric drives. Low cost, construction simplicity and
reliability are the motives that explains this statement. For the induction motor control
was applied the control strategy known as Field Oriented Control and for the estimation
of the motor rotor speed was used an artificial neural network, which observer electrical
and mechanical system variables. The practical results were satisfatory, since the neural
network worked for the measeured and estimated velocity, being possible to perform the
control os the motor with the estimated speed in the range of 100 to 170 rad/s. |
