feedback control


Also found in: Acronyms.

feedback control

(electronics)
A control system which monitors its effect on the system it is controlling and modifies its output accordingly. For example, a thermostat has two inputs: the desired temperature and the current temperature (the latter is the feedback). The output of the thermostat changes so as to try to equalise the two inputs.

Computer disk drives use feedback control to position the read/write heads accurately on a recording track. Complex systems such as the human body contain many feedback systems that interact with each other; the homeostasis mechanisms that control body temperature and acidity are good examples.

In addition to expanding capacities, the Multi-lane Checkweigher feedback control function minimizes product weight errors through proactive feedback per lane or a combined feedback for all lanes to keep filler heads properly adjusted.
In Section 3, we design the strategy of SMC with delayed-output observer to suppress the effect of flexible deformation and analyse its performance in the force feedback control. In Section 4, we assess the performance of the force feedback control and search for the optimal length of guide wire between the actuator and human hand.
