Abstract :
This paper proposes a networked sliding mode controller for servomechanical systems. Asymptotic stability is analyzed. Saturation function is used to eliminate chattering. Sensitivity of the zero eigenvalue with respect to the gain of the saturation function in linear interval is analyzed. Conditions for the choice of the gain and time delay are proposed. Simulations are conducted to verify the theoretical results.
