Abstract
A control device for a process, in which a controlled variable can be influenced with the aid of a plurality of different regulating units, which in particular are based on different physical principles. A set point and the controlled variable are fed to both a first controller and a second controller. The first controller is located as primary controller in automatic operation and has a regulating range of the first manipulated variable that is defined by limiting values. The second controller can be switched between automatic operation and tracking operation, in which the controller generates a predefined or predefinable constant value of the second manipulated variable. By means of a logic circuit, the second controller is switched to automatic operation if a limiting value of the first manipulated variable is reached, and otherwise to tracking operation. Advantageously, by means of the control device, a plurality of regulating units which have the same direction of action can be operated fully automatically and autonomously.
