ANN CONTROL SYSTEM FOR ROTOR RESISTANCE ESTIMATION OF INDUCTION MOTOR

摘要

This invention relates to a rotor resistance estimated by using the ANN controller 10 depending on the operating conditions of the electric motor of as a load of the output from the error that appears between the output and uses the demand state model and the actual state model of the ANN model (9) of the actual induction motor (4) for the rotor resistance estimate ANN model of the invention (9) the radio station in order to control the . Therefore, the output of the ANN model match sikimeuroseo 9 and constitutes the actual model ANN controller 10 to estimate the rotor resistance . Representative systems configured as shown in Fig constant speed , step change in command speed , a variety of speed change , the estimation of the load change , and four-quadrant operation , such as the rotor resistance with respect to the increase and decrease of the actual rotor resistance in a variety of performance parameter changes It represents .
