Abstract

With the higher-order sliding mode control theory, a quasi-continuous high-order terminal sliding mode vibration control method is presented for a centrifuge force-vibration test system in presence of parameter variations and external disturbances. First the basic idea of the higher-order sliding mode control is introduced, then the centrifuge force-vibration test system mathematical model is described and two-order terminal sliding modes are designed to make the motor speed, final the higher-order sliding mode vibration displacement control law is derived based on Lyapunov second method. The simulation results show that the motor speed can reach the given value more rapidly than that of a general slide-mode control and the method effectively weak chattering and achieve vibration tracking maneuver precision positioning, and have higher precision and reliability.


Key words
