Designing Control Systems with Knowledge

It is generally accepted that object-based systems provide a simple and elegant paradigm for general-purpose programming that meshed well with data models. In this paper we propose to use the object computation model as the basis for automatic control system design environment. Typically, an automatic control system design environment consists of a set of control system design experts that cooperate with each other. In addition to experts there are a number of control systems that have been designed or are to be designed. We propose to construct a knowledge base between such an environment and the users of the environment; Consequently a user sees the environment as a large knowledge base, and he or she can create, modify, retrieve, or query the knowledge base through knowledge base operations. Furthermore, the knowledge base can help the users to manage the inter-relationships between entities that reside in the environment, to represent abstract knowledge about control system design, and it can derive more knowledge about a plant once a minimal set of characteristics is provided.
