This article presents a robust control method for trajectory tracking and balancing of ballbot with uncertainty. Since the is an underactuated system, previous studies have designed controllers using hierarchical strategy and/or multi-loop approach. However, systems require several has local minimum problem that does not guarantee convergence all errors globally. To overcome these drawbacks, we introduce virtual angle design sliding mode controller single-loop system. As result, proposed...
