This is referred to as a critically damped control loop [Figure 8]. Assuming the electrical and/or software aspects have been correctly implemented, the fan control loop response depends entirely on ...

4-wire DC fans include hall-effect sensors that sense magnetic fields generated by the rotor as it spins. The output of the hall-effect sensor is a pulse train that has a period inversely proportional ...

Finding and fixing process control loop problems that PID tuning cannot correct By Mark Coughran Plant engineers and technicians are frequently asked to tune the controller when a control loop’s ...

Proportional-integral-derivative (PID) is the most common industrial technology for closed-loop control. A proportional-integral-derivative (PID) controller can be used to control temperature, ...

If you don’t think control systems are everywhere, consider an example we use when talking to school kids: a toilet. A very simple and very common closed loop control system.

Self-regulating systems with feedback loops, i.e., the routing back of the output of a system to its input, have existed since antiquity and have since become an integral part of modern technology.
