Conventional servo systems, to ensure machine performance, smoothness, positional error and low servo noise, require the adjustment of its servo’s gains as an initial crucial step. Even systems that employ auto-tuning require manual tweaking after the system is installed, especially if more that one axis are interdependent. Ezi-SERVO® employs the best characteristics of stepper and closed loop motion controls and algorithms to eliminate the need of tedious gain tuning required for conventional closed loop servo systems.
Hearing the article of his faith defamed by its creator produced a negative feedback loop in Neel so strong his hands vibrated in tune with it. It took a jarring effort to crack out of the cycle. "The laws that control Societics, as postulated by … you, are as exact as any others in the unified-field theory universe." "No they're not. And, if any man I taught beli
The amount that each of these elements contribute to the control must be adjusted to correspond to the process being controlled. This adjustment is known as "tuning" the control loop. An incorrectly tuned loop will not function correctly, providing less than the desired performance. We will first look at how to determine if a loop is properly tuned and then cover some of the typical methods of tuning loops.
Excessive inflammatory responses can be horribly destructive.
Unsurprisingly, therefore, immune responses are dampened down
and fine-tuned in a multitude of ways to minimize their damaging
effects. Four articles in this issue provide examples of such
immune regulation on four different levels.
Wolfgang Junger (page 201) explains that cells take it upon themselves
to control their behaviour to extracellular cues through autocrine feedback
loops involving purinergic receptors.
