Variable sampling period introduces variable delay. That delay should be taken into account when tuning the controller. The resulting gains of the controller are adjusted on the fly. You might call it ...

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 ...

Encoders are a vital component in many applications that require motion control and feedback information. Whether a system’s requirement is speed, direction, or distance, an encoder produces control ...

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 ...
