Nonsingular BLF-Based Simultaneous Tracking and Balancing Control of Uncertain Ball-Balancing Robots With Moving Obstacles: A Virtual-Angle Approach
This paper proposes a nonsingular virtual-angle control method for uncertain underactuated ball-balancing robots (BBRs) subject to trajectory tracking, posture stabilization, and obstacle avoidance requirements. Because tracking and balancing are strongly coupled in BBR systems, conventional hierarchical sliding mode c...
