Watch Again | Control and Communications Ireland Joint Chapter Webinar – Learning-based Fixed-time Control for Collaborative Robots subject to Physical Constraints by Dr Mien Van, Queen’s University Belfast

Robotics have been extensively applied for many practical applications such as manufacturing, agriculture and ocean exploration. To increase the performance of robots for these applications, concepts of human-robot interaction/collaboration and multiple collaborative robots have been extensively studied.

However, robotics working in uncertain and unstructured environments will inevitably encounter unanticipated situations during their operation because of the effects of model uncertainties and environmental disturbances, which reduce the resilience and safety of the system. In addition, the constraints on control efforts, states and safety boundaries limit the flexibilities of the design of control inputs.

This presentation introduces new findings about fixed-time control techniques for robotics systems subject to physical constraints, for instance  input saturation, working space constraints and obstacle avoidance to increase the response and convergence of the system.

Learning methods based on neural networks are also introduced to approximate the model uncertainties and disturbances and incorporated into the fixed-time controllers to increase the performance of the system.

Finally, applications of the learning-based fixed-time controllers for physical human-robot collaboration (pHRI) and multiple collaborative autonomous underwater vehicles (AUVs) are discussed.
