A knowledge based intelligent controller (for process applications)

The paper demonstrates how AI techniques, namely the expert system approach, can be combined with a parallel process control scheme to implement a redundancy robust knowledge based intelligent controller. The knowledge base for this controller was designed to make a decision to select between a number of control strategies running in parallel based on specified control objectives. The parallel control structure provides both a means of reliability through redundancy and wide ranging applicability due to the variable control structure capability.
