Definitions for "PID Control"
Control in which the control signal is a linear combination of the error signal, its integral, and its derivative.
Proportional plus Integral plus Derivative control is used in processes where the controlled variable is affected by long downtimes.
Actions used to correct the difference between a controller setpoint and the required setpoint. This method controls modulating equipment for example, valves, dampers, and other control elements. PID actions provide control stability and quick response to minimize setpoint error. PID control elements include proportional control, integral action, and derivative action. See proportional control. See integral action. See derivative action.
