Paper Title
Robust Control of Two-Axis Pan-Tilt System

In this paper, a robust control method is proposed for a two-axis pan-tilt system. A sliding mode based nonlinear controller is introduced for joint position tracking control of the pan-tilt system. Finite-time stability of the closed loop system is proved by using constructive Lyapunov stability analysis. Experimental result shows the effectiveness of the proposed chattering-free SMC method.
