Controle de velocidade em sistemas de acionamento com máquinas assíncronas.

Abstract

This work presents a study of motor drive for asynchronous squirrel cage machine. This system is operated as variable speed drive with various control strategies of flux and torque decoupling. The drive control system contains an inner loop to insure a constant air-gap flux. The air-gap is assured by real time estimation using stochastic filtering. The Kalman discrete filter is developed of the asynchronous machine. An AC motor drive system is developed to be used in laboratory. This system may implement the strategies studied in a real time operation. All the discrete algorithms were developed to be implemented on a Digital signal processor (TMS32010) based set up.
