PID controller |
(PID) |
The controller calculates the output value from the difference between the Setpoint and the Actual Value.
The control parameters are Proportional Coefficient, Integral Time and Derivative Time.
S | Setpoint | Target value of controller, e.g. target room temperature |
A | Actual value | Current measured value |
PC | Proportional Coefficient | Controller gain |
IT | Integral Time | Integral time in [s]; typical range: 60...900 s |
DT | Derivative Time | Derivative Time in [s]; typical range: 1...10 s |
R | Reset | Triggers the integral value of the controller |
O | Output |
