Issues on Applying Knowledge-Based Techniques in Real-Time Control Systems
Keywords:Real-time control systems, knowledge-based systems, Programmable Logic Controller
At the time being knowledge-based systems are used in almost all life aspects. TheÂ main reason for trying to use knowledge-based systems in real-time control is toÂ reduce cognitive load on users (overload), their application proving to be importantÂ when conventional techniques have failed or are not sufficiently effective . TheÂ development of automated diagnosis techniques and systems can help also to minimizeÂ downtime and maintain efficient output. This paper presents some issues of applyingÂ knowledge-based systems to real-time control systems. It describes and analyzes theÂ main issues concerning the real-time domain and provides possible solutions, suchÂ as a set of requirements that a real-time knowledge-based system must satisfy. TheÂ paper proposes a possible architecture for applying knowledge-based techniques inÂ real-time control systems. Finally, a way of employing knowledge-based techniques Â for extending the existing automatic control and monitoring system for the geothermalÂ plant from the University of Oradea is presented.
