7.13. CONTROLLERS
Although most controlling processes can be realised using simple ON - OFF mode,
there 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 is 8 independent settings of PID type controllers available.
