Control of beam vibrations by means of piezoelectric devices: theory and experiments

摘要: Abstract The problem of the attenuation vibration effects in active cantilever beams has been approached by two strategies, position and velocity control, which have simulated numerically analysed experimentally. numerical simulation developed means a finite element approach based on an Euler–Bernoulli model subsequent modal factorisation. Each device as well each electronic circuit, present single-input single-output control system modelled results simulations compared with ones obtained experimental tests. A good correspondence all examined cases.
