| Abstract |
The paper reviews the technology status and
recently developed control strategies for PWM rectifier
inverter-fed induction motor drives with emphasis for its
similarities. A comprehensive review includes: new PWM
techniques, field oriented and direct torque control of
induction motor (FOC and DTC), voltage oriented and
direct power control of PWM rectifier (VOC and DPC),
novel virtual flux (VF) based sensorless control of PWM
rectifier. Also, neural network and fuzzy logic based intelligent
controllers for motion control has been discussed.
Selected oscillograms accompany the presentation in
order to illustrate properties of the described control
strategies. |
