Closed loop refers to a regulator circuit in which the actual value of the controlled variable (e.g., speed) is sensed and a signal proportional to this value (feedback signal) is compared with a sign [..]

The speed of a motor is regulated by using the feedback from an encoder or tachometer.

In a control system, a type of control that has an input signal and a feedback of the result of the input signal which is used to modulate the input signal automatically. See OPEN LOOP.

Closed loop controls use feedback to correct for errors in the system. Central heating in a building is a common example. The thermostat measures the temperature and turns the heat on or off as necess [..]

Contiguous sketched lines or edges. Can be selected by double-clicking one of the edges or lines.

A control system that continually monitors the process, receives feedback of process changes, and then outputs corrections to a final control element to maintain a set point value.

refers to those times when an EFI computer is using the feedback on the mixture provided by the oxygen sensor to effectively control the injected amounts.

A closed circuit where the fluid is recalculated.

A system that measures the output and adjusts operation based on conditions. This is also known as feedback. See also: Open Loop

A heat collection system whereby a pipe-work system is placed within the ground (or lake, river sea) and water/glycol mixed is circulated through it. A heat pump will then extract heat from the circul [..]
