Abstract :
In this paper a second order sliding mode controller is proposed for controlling systems with mismatched uncertainty. Stability of the system is guaranteed and the chattering in the control input is considerably reduced. Simulation results demonstrate the superiority of the proposed controller over the existing first order sliding mode controller designed to handle mismatched uncertainty.
