Περίληψη

Smart structures include elements of active, passive or hybrid control. For compli- cated structures, mainly the ones including nonlinearities, or nonlinear control laws, the theoretical results from the area of control are not very helpful. In this paper, the fuzzy control is considered, which is a suitable tool for the systematic development of active control strategies, and the Differential Evolution algorithm is proposed and used for the calculation of the continuous and discrete free parameters in the fuzzy control system. Numerical applications for smart piezoelastic beams are presented. The results obtained are compared with the ones obtained with the fuzzy controller optimized using Particle Swarm Optimization and with the fuzzy controller optimized using a Genetic Algorithm.
