In modern mechanical contructions active damping seems to be essential. But real mechanical contructions are complicated in shape and are composed of components with distributed parameters. That is why advanced modeling techniques should be implemented in the process of designing of vibration control system. In this paper we design a vibration control system for cantilever beam. As a sensor of the beam movement and as an actuator we use piezoelectric elements coupled with hardware of dSpace and software of Matlab-Simulink. The relations describing influence of piezo-actuator on the beam bending has been found. Measurement equation for piezo sensor was also prepared. Control system was designed for a few controlled modes. The influence of control system on non-controlled modes is considered.
