Ballbots are versatile robotic systems with the ability to move around in all directions. This makes it tricky to control their movement. In a recent study, a team has proposed a novel proportional ...
The schematic of a PMSM drive using a DTC-based speed loop PDFF controller is shown in Fig. 1. This DTC scheme is implemented in stator flux frame, which requires knowledge of stator flux in ...
The proposed controller for ballbot devices enhances the adaptability to dynamic environments via self-learning and self-adjusting characteristics. Ballbot is a unique kind of robot with great ...
