| Abstract |
This paper presents a feas ible development on a highly accurate quick response
adjustable speed drive implementation for general purpose induction motor which operates on
the basis of sensorless slip frequency type vector controlled sine -wave PWM inverter with an
automatic tuning machine parameter estimation schemes.
In the first place, the sensorless vector control theory on the three-phase voltage source -fed
inverter induction motor drive system is developed in slip frequency based vector control
principle. In the second place, the variable speed induction motor drive system, employing
sensorless vector control scheme which is based on three-phase high frequency carrier PWM
inverter with automatic tuning estimation schemes of the temperature -depende nt and
-independent machine circuit parameters, is practically implemented using DSP-based
controller. Finally, 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. |
