Galil Automates Extraordinary Artwork: The Sonic Plaza at East Carolina University

by annk

It’s almost midnight on campus and a group of college students are walking back to their dorm rooms after a long night of studying. As they move toward the University’s plaza entrance, they pass through the library’s columns and are surprised by sounds that emanate from overhead, creating a consonant harmony that changes in pitch and timbre. They look towards the plaza and see a large misty c

Using Notch Filters to Compensate for Resonance in Servo Motor Control Systems

by Galil_LisaW

Servo motor control systems with resonance often create difficult problems for designers because it causes the servo control system to over-shoot and oscillate.

An effective way to compensate for resonance in a servo system is the use of a notch filter in addition to the standard PID servo loop compensation. To understand the operation of a notch filter, note that every resonance is characterized by two parameters: the imaginary and the real part. The imaginary part sets the resonance frequency, whereas the real part sets the damping. The smaller the real part, the stronger the effect of the resonance.

Minimizing Servo Motor Temperature in Optimal Design of Motor Control Systems

by Galil_LisaW

The ability of a servo motor to perform the required moves within short times is limited by the temperature rise that results from the power dissipation. It follows, then, that the optimal design of a servo motor control system, which maximizes the system throughput, is the one that results in minimum servo motor temperature.

This post addresses the optimal design of a servo motor control system. It assumes a required motion of given length, and seeks the design that accomplishes the required move within a specified time, while minimizing the servo motor temperature.
