The information presented here is generally known to dc motor manufacturers but is not common knowledge to dc motor users. As there is a necessity for the equipment to perform beyond its original specifications and adjustment, commutation issues may arise that could increase maintenance requirements or downtime.

We derive the mathematical model of this class of motors. Then we design the proposed control schemes in original coordinates, i.e. a dq transformation is not required. We formally solve the velocity and position regulation problems. A pendulum is included as the load in the position control problem. In this chapter we include sketches of the stability

Experiments with an electric motor provide good opportunity to demonstrate some basic laws of electricity and magnetism. The aim of the experiments with a low-power dc motor is to show how the motor approaches its steady rotation and how its torque, mechanical power and efficiency depend on the rotation velocity.

DC motor velocity control through a DC-to-DC power converter
2004 43rd IEEE Conference on Decision and Control (CDC) (IEEE Cat. No.04CH37601), 2004This paper considers the development of a smooth "starter" for a DC motor based on a switch controlled DC-to-DC power converter of the "buck" type. The dynamic feedback controller is based on a suitable combination of passivity based control, flatness and a /spl Sigma/ - /spl Delta/ modulator implementation of the average designed controller.

DC motors remain very important for control system applications in two main areas: (a) High-power drives where precise variable-speed control is required. (b) Servomechanisms. Although AC machines, in conjunction with solid-sate electronics have made great progress, DC machines have also been the subject of improvement.

In this chapter, we’ll develop a diozero-based device library based on what you learned in earlier chapters. I’ve chosen a device commonly used in robotics, a DC motor controller, and, more narrowly, one accessed via serial I/O. That said, the chapter covers topics applicable to the development of a device library for any type of device using any form ...
