CONTROLLERS
Most controlling processes can be realised using a simple ON - OFF mode, however it is
sometimes necessity to use more advanced methods to control the actuators. The MultiCon
has implemented
proportional–integral–derivative controllers
(
PID controllers
) which is a
generic control loop feedback mechanism (controller) by calculating an "error" value as the
difference between a measured process variable and a desired setpoint. The controller
attempts to minimize the error by adjusting the process control outputs. In the device there
are 8 independent settings of PID type controllers available.
