Abstract: This paper deals with the dynamics and adaptive control of a piezoelectric micro-electromechanical device without and with discontinuity. The modelling of the device with a discontinuity is carried out and its dynamics is studied using the bifurcation diagram to observe the regions of periodic and chaotic motions. The Lyapunov theory is used to design adaptive controllers to restore the prescribed dynamics of the system when it is subjected to a short variation of one of its parameters. The efficiency of the controllers is tested using numerical simulations.
