|Sliding Mode Control Design for Mismatched Uncertain Systems Using Output Feedback
International Journal of Control, Automation, and Systems, vol. 14, no. 2, pp.579-586, 2016
Abstract : This paper develops an output feedback sliding mode control law for linear MIMO systems having
mismatched parameter uncertainties along with disturbances and matched perturbations. Both quadratic stabilization
and static output feedback control techniques are introduced into the sliding mode controller. The proposed
output-dependent sliding surface can guarantee robust stability of the closed-loop system and achieve disturbance
attenuation when the system is in the sliding mode. The existence condition of the sliding surface is determined
by solving the coupled algebraic Riccati equations which involve the original system parameters. The developed
output feedback control law can guarantee that the system globally reaches and is finally maintained on the sliding
surface in finite time.
