Improved dynamic behaviour of a sensorless stepping motor load angle estimator based on Transfer Function Analyzer technique

The performance and robustness of a sensorless controller strongly depends on how quickly and accurately the feedback is obtained. For this reason, the purpose of this paper is to introduce an improved load angle estimator that provides feedback on the ability of the stepping motor to follow the imposed position/speed setpoint. The novel estimation dynamics is compared theoretically and experimentally with dynamics of similar estimators.
