Abstract
In this paper, we consider the second-order sliding mode stabilization control problem for the rotary inverted pendulum. The rotary inverted pendulum is a class of two-degree-of-freedom underactuated systems, since its motion consists of rotary arm and pendulum angles, but only the rotary arm is subjected to the control input. We first introduce the new sliding surface, which is designed to resolve the underactuation problem by combining the pendulum dynamics with the rotary arm dynamics. Then, for the pendulum stabilization, we develop second-order sliding mode control based on the super-twis
