Abstract:
A control device for a process that influences the process via a manipulated variable in accordance with a control deviation between a setpoint and a controlled variable influenced by a disturbance variable, includes a controller that produces the manipulated variable from the control deviation fed to the controller, a controller dead zone element arranged before the controller and which can be activatable/deactivatable via a control apparatus, where the controller dead zone element is deactivated when the control deviation exceeds a first threshold value and reactivated when the control deviation falls below a second threshold value that is less than the first threshold value, and includes an adding element that contains a low-pass filter and preferably a disturbance-variable dead zone element arranged after the low-pass filter and which produces an auxiliary manipulated variable from the disturbance variable and adds the auxiliary manipulated variable onto the manipulated variable.
