In motion control applications, you frequently hear all sorts of loops -- open, closed, current, torque, speed, voltage, and so on. Here, we define and explain these terms.

A control loop can be causing its own oscillation, or it could be affected by an interacting oscillation somewhere else in the process. A simple way to determine if the origin of the oscillation lies ...

The Control Loop. Don Morgan. Tuning a PID controller is pretty straightforward, once you know how to start and what steps to follow. In this series on motion control, we have already discussed ...

Control loop performance-monitoring software can help to improve loop performance at electric power plants by automatically collecting data, assessing several aspects of loop performance, and ...

Using a loop compensation tool, one solution would be to decrease the gain until the output impedance appeared constant, or until the current spikes had gone (Figure 4). In this case example, with ...

The control loop must have sufficient gain and bandwidth to quickly adjust the duty cycle up or down as the FET transitions on and off. The output voltage swings between 10.5 volts and below 0.1 volt, ...
