Checking the Stability of a Fuzzy Controller for Nonlinear Structures

Standard strategies of active control were applied recently to civil engineering structures excited by environmental loads such as wind and earthquake. Attempts to overcome some technical inconvenience by the exploitation of suitable nonlinearities are in progress. Fuzzy controllers are potential candidates to drive the control in the presence of these structural nonlinearities. This paper pursues the identification of the stability checks to be conducted within the design process of such a fuzzy controller.
