Common approaches in vector control design of induction motor and permanent-magnet syncronous motor

Abstract

The article describes a way to generalize current control loop structure for AC drives, by implementing general PI gains calculation block. Article contains block diagram of generalized current control loop for smooth-air-gap and salient-pole machines. Electromagnetic torque estimator is represented, whose design based on stator voltage and current measurements. Results of simulation modeling of electromagnetic torque estimator in pair with field-oriented control are represented.
