Indirect Stator-Quantities Control (ISC) combines the principle of stator-flux-orientation proven successful in Direct Self Control (DSC) with Pulse-Width Modulation (PWM). High torque dynamics and robust behaviour against input voltage disturbance are achieved in the whole operation range including field-weakening. After careful correction of inverter-voltage errors and dc portions in the stator...
In this paper the influence of the non-ideal behavior of power electronics, sensors, and signal processing on pulse signal injection based speed sensorless control is addressed and investigated. The speed sensorless control signals are obtained from the transient current response resulting from an excitation of the machine with voltage pulses. The investigation is focused on sensorless control of...
