434 Swing-Up of Inverted Pendulum by Using both Vertical Axis and Horizontal Axis

The invert pendulum is often used to confirm the control theory and a new control design, because it is unstable system and an experiment on it is easy. This paper has a discussion about a swinging-up problem of the inverted pendulum. While usually an inverted pendulum is swung up by the horizontal movement of a cart, we propose a new swing-up method by both a horizontal and vertical movements of a cart. The movement of a cart is defined to increase energy of a pendulum. With the proposed method, a time for swing- up is shortened. An effectiveness of the proposed method is confirmed though the experiments. Since the proposed swinging-up control does not use system parameters for example a mass and a length of pendulum, the proposed control has robustness against parameter fluctuation.
