Control and Synchronization of Gyroscopes with two degrees of freedom Using Sliding Mode Control

Gyros for recognizing angular motion are used in vessel’s gyrocompasses، submarine inertial، airplane automatic pilots and space-vehicle attitude systems. The dynamics of gyro is a very exciting nonlinear problem in classical mechanics and control engineering. In this study، control and synchronization of two gyroscope systems with two degrees of freedom is studied. It is shown that the mentioned gyroscope system has nonlinear and chaotic dynamics. For tackle the problems of nonlinearities and chaotic behavior، in this research sliding mode control (SMC) is proposed for control and synchronization purpose. The simulation results confirm that sliding mode based controller provides good synchronization without chattering phenomena.
