Adaptive Sliding Mode Control of the Linear Drive System

Abstract:

An adaptive sliding mode controller (ASMC) is designed for the linear drive system. The control law is expressed as a function of the disturbance which is predicted from the motor current and the active damping of the measured structural modes. Accurate prediction of the disturbance is used to actively compensate the low frequency machine tool structural modes which are within the control bandwidth. Compared with the cascaded controller (CC), the designed ASMC not only has greater control bandwidth, stronger anti-disturbance and robustness, but also improves the dynamic stiffness of the linear drive system significantly.
