Design, implementation and performance evaluation of a real-time knowledge-based controller

The general structure and design specifications of a real-time knowledge-based controller are proposed. The knowledge-based controller has been designed, implemented, and evaluated for a hydraulic turbine generator control system. The controller has been designed to maintain the system stability and performance not only during normal plant operation, but also in the presence of contingencies, such as system component failures and severe external load disturbances. The knowledge-base and the inference engine software are written in Prolog, and the information preprocessing and control algorithms are written in C language. The performance of the knowledge-based controller has been evaluated by simulating the hydraulic turbine generator system on an analog computer with the knowledge-based controller implemented in real time on a microcomputer
