Fuzzy control optimized by PSO for vibration suppression of beams

Smart structures include elements of active, passive or hybrid control. In this paper, particle swarm optimization (PSO) for the calculation of the free parameters in active control systems is proposed and tested. Especially, the fuzzy control is considered, which is a suitable tool for the systematic development of active control strategies and can be fine tuned if no experience exists or if one designs more complicated control schemes. The usage of PSO with a combination of continuous and discrete variables for the optimal design of the controller is proposed. Numerical applications on smart piezoelastic beams are presented.
