1 Introduction
The system of the ball and plate is a two-dimensional electromechanical system intended for a study of the dynamic systems and laboratory experiments with different proceeding of the control based on the classical and modern control theory. The system includes the quadratic metal plate, which is movably fixed in the center. Its inclination can be changeable in two rectangular directions. For the inclination of the plate a servo-drive with a controller and stepping motor is used [5].
