Abstract
In an adaptive control system, an input of an object to be controlled is varied by a small value, and a resultant output is detected. The small value is changed on the basis of the difference between the output and an aimed value, and trials are repeated. The small value is determined on the basis of a qualitative model which is composed of a boundary function including the input and boundary parameters of the object. If the trend in the difference between the output and the aimed value is to make it larger, the qualitative model is changed so that the trend is to make it smaller.
