The paper concerns a class of knowledge-based control systems containing a controller with inputs and outputs assumed to be values of uncertain variables. The description of the controller then has the form of certainty distribution of these variables. Two general approaches to the knowledge-based design of such a controller are presented: in a prescriptive approach expert's knowledge concerns a controller and in a descriptive approach expert's knowledge concerns a plant. A method for evaluating control quality obtained with both approaches is proposed, and a concept of controller's adaptation is presented. Numerical example and results of simulations are included.
