Recently fuzzy control has been applied to various systems such as home electronics, the process, and plants. Because applications to actual control systems can be risky, the stability of fuzzy costrol system must be insured. As stability analysis of fuzzy control, phase plane analysis, Hurwitz's analysis in subareas, and Lyapunov's method have been proposed. In this paper, we propose a new method of stability analysis, that is, stability discrimination on the basis of display of the stability area in 3D space, the manipulated variable, the control error, and the deviation of its error.
