Abstract :
This paper proposed a simple graphical criterion for stability margin determination of closed-loop control systems contained plant with fuzzy coefficients. The stability margin shows that what plant fuzziness can be large without system destabilization. The presented method is generalization of obtained result in robust stability analysis and can be applied in the case of trapezoidal or triangular membership functions.
