Semantic Control Of Chemical Processes

Semantic control theory (SCT) deals with large scale control problems when formalization of the knowledge about the plant which is the object to be controlled and about the method of control are particularly difficult, and, therefore, the classical control-theoretic methods are not applicable. The classical framework of reference which the designers of control systems employ involve the following logical sequence: 1.) Describe the object to be controlled; 2.) Describe the goals of the object; 3.) Construct the performance measure corresponding to the goal; 4.) Analyze mathematically the model postulated above; 5.) Apply the results to design the control system.
