Abstract: The position update time increases when the motor with a low-resolution position encoder runs at a low speed. Therefore, a considerable speed calculation delay is generated, and the ...

Encoder tracking is a technique that monitors a reference motor with an encoder and controls a secondary motor. The method provides programmable motor-to-encoder ratios that determine relative speed ...

A high-accuracy 20-bit resolution quasi-absolute encoder with DSP-based signal processing is housed in a dc stepper motor assembly, as shown in Fig. 1. Able to operate in a temperature range between ...

Abstract: In this paper, the performance of a new speed and disturbance torque observer applied to the closed loop control of an induction machine is studied. The main novelty is that the analysis of ...
