For controlling an industrial process (12), a conventional controller (33), particularly a controller based on Model Predictive Control, is configured to calculate manipulated variables (u C ) for controlling the process (12), based on process variables (y). The controller (33) is combined with an expert system (31), which determines output values (u 1 , u 2 , u N ) for controlling the process (12), and a selector (32), which selects either the manipulated variables (u C ) or the output values (u 1 , u 2 , u N ) for controlling the process (12), based on operating conditions of the process. Using an expert system (31) to interrupt a conventional controller (33) from controlling an industrial process (12) has the advantage that a much broader range of operating conditions and emergency situations can be handled than with the conventional controller (33), and a wide range of predefined actions can be triggered for returning operations to a designed operating range of the conventional controller (33). |
