Summary
In this paper a smart composite plate with delamination to the piezoelectric layers is considered. First a nonlinear damage model is introduced so that stress and strain, including delamination, can be calculated. For the design of fuzzy controllers, three different cases of delamination are investigated. Namely, the cases studied include 10, 50 and 90 percent delamination of the piezoelectric material. The controller was initially designed for non-delaminated structures. However, the simulation shows that this type of control provides satisfactory results for delaminated structures as well, even in structures with high percentage of delamination. The models and the controller were built within the MATLAB environment.
