Abstract

The paper proposes a stability analysis method based on the application of the center manifold theory belonging to the state-space methods to the stability analysis of fuzzy control systems. The methods considers a linearized mathematical model of the second order nonlinear plant, and its only constraint is in the smooth character of the right-hand term of the state-space equations of the controlled plant. The method is exemplified by applying it to the stability analysis of a state feedback fuzzy control system meant for the position control of an electrohydraulic servosystem.KeywordsFuzzy ControlFuzzy ControllerFuzzy Control SystemCenter Manifold TheoryTrapezoidal Membership FunctionThese keywords were added by machine and not by the authors.
