| Product Description :
||The PID Controller is a generic control loop feedback mechanism and is widely used to rectify the fault between a deliberate procedure variable & desired ones and gives a remedial action. The PID controller calculation (algorithm) involves three separate parameters; the Proportional, the Integral and Derivative values. The Proportional value determines the reaction to the current error, the Integral determines the reaction based on the sum of recent errors and the Derivative determines the reaction to the rate at which the error has been changing. And this is used to adjust the process via a control element such as the position of a control valve or the power supply of a heating element.
