High-Bandwidth Sensorless Algorithm for AC Machines Based on Square-Wave-Type Voltage Injection

This paper describes a new control algorithm which can enhance the dynamics of a sensorless control system and gives a precise sensorless control performance. Instead of the conventional sinusoidal-type voltage injection, a square-wave-type voltage injection incorporated with the associated signal p...
