METHOD FOR CONTROLLING A TIME-LAGGED PROCESS WITH COMPENSATION, AND A CONTROLLING DEVICE FOR CARRYING OUT SAID METHOD

摘要

A method is described for the closed-loop control of a time-delayed process having compensation, in particular for temperature control. After a setpoint value step-change, the manipulated variable is set at a first constant value in an open-loop controlled operation, an IT1 model is identified on the basis of the step-change response and a PI controller is parametrized, which closed-loop controls the process into a second steady state. Subsequently, a more exact process model having compensation is determined and is used for the control adjustment.
