In general, it is difficult to design a control system which satisfies completely all demanded design specifications for the control system, because these design specifications are ambiguous and contradict each other. in this paper, to make the design specifications clear, we apply the fuzzy division which has been used in the fuzzy control theory in the treatment of design specifications for linear control systems. That is, we choose the phaseplane as the appropriate designing space which has relation with these specifications and fuzzily divide this phaseplane according to these specifications. In the each fuzzily divided region, we decide the proper control which satisfies the cleared design specifications. And then, the total control for the control system is constructed by the weighted control which is decided properly in the each fuzzily divided region. Lastly, we apply this design method to the linear regulator in problems.
