Application of interactive multiobjective satisfaction to control system design.

A new satisfaction method is composed mainly of two ideas : the techniques for judging the existence of the solution satisfying the permitted limit ; and the setting and correcting of the value of the permitted limit, based on interactive information with the designer. This method is applied to a computer aided design of a control system. Computer aided control system design, using the model following control method, is composed of both the decision process of the desired transfer functions and decision process of the control system. The decision process of the former has not been very clear until now. If this process is aided by the proposed satisfaction method, the desired transfer functions can be determined systematically and efficiently. The proposed interactive method is applied to actual systems in order to confirm its efficiency. The proposed interactive method applied to actual systems in order to confirm its efficiency. The first example is the control system design for a 60, 000 ton tanker, and the next is for a refrigerating machine.
