UTILIZATION DEVELOPMENT OF SPEED SENSOR-LESS ECTOR CPNTROLLED INVERTER WITH THE NOVEL UTOMATIC TUNING SCHEME OF THE INDUCTION OTOR PARAMETERS

摘要

This paper presents a feasible development on a highly accurate quick response adjustable speed drive implementation for general purpose induction motor which operates on the basis of sensor-less slip frequency type vector controlled sine-wave PWM inverter with an automatic tuning machine parameter estimation schemes. As the conclusion, the dynamic speed response performances for largely changed load torque disturbances as well as steady state speed vs. torque characteristics of this induction motor control implementation are illustrated and discussed from an experimental point of view.
