Fan control is an important aspect of system architecture. Though often left as a secondary activity, its implementation has significant effects. Customer response can be immediate to factors such as ...

DriveSure pumps from Watson-Marlow utilize digital closed-loop control technology for accurate, energy-efficient operation across varying pressures and viscosities. Their design reduces contamination ...

Take a look at mechatronics' applications in diverse industries, such as automotive engine systems, hard-disk drives and Web-transport systems, and you'll find a growing emphasis on "sensorless ...

Many applications in test and measurement take advantage of feedback to improve some aspect of performance. In simple power-sourcing instruments, for example, you can use the fact that, given the ...

Switching power supplies rely on feedback control loops to ensure that the required voltage and current are maintained under varying load conditions. Design of the feedback control loop influences ...

This White Paper will explain the three methods that are used to close the feedback loop around stepper motors in a control system. These three methods include ways to close the loop around a stepper ...

Every plant in the process industry most likely has several control loops that do not perform well. Although there are many factors that may negatively affect control loop performance, a few of these ...

The goal of controlling a system is to reach or retain stability. In control theory, stability is described with the Lyapunov stability criteria and mathematical models that set into relation the ...
