Graphical stability analysis of a fuzzy control system
R. Katoh, Tadashi Yamashita, Sukhbir Singh · 2002
Stability of fuzzy control system is analyzed wherein control system with two inputs and single output is transformed to two inputs and two outputs control system which in turn is transformed to Lure system having a linear plant and nonlinear controller by checking the stability of the linear part of the control system. A new graphical method, which consists of three procedures, has been proposed to analyze the absolute stability of the fuzzy control system. The method is shown correctly using an example, and effect of plant parameters on the stability have also been studied.>
