In the daily life and techniques people all time have interaction with continue media like air and water flow. Very large achievements in mechanics of the field of aero and hydro dynamics achieved. In the same time there are many technical tasks to be solved. One of the tasks group is optimization of form and parameters of technical objects with a criteria of energy saving or its useful utilization from interaction with air or water flow. In this report motion control by area exchang of vibrator with constant airflow excitation in system with one and two degree of freedom is investigated. Key words: motion control, air excitation, optimisation, adaptive control, synthesis.
