Nonlinear Output Regulation: The Internal Model Approach

Dabo Xu, Nanjing University of Science and Technology

Abstract:Output regulation is a central feedback control problem that aims at addressing asymptotic tracking and/or disturbance rejection, while maintaining stability of the closed-loop system. The popular problem formulation is general enough to cover stabilization, asymptotic tracking, output synchronization, and disturbance rejection as rather special cases. In general, for solving the problem by smooth error-output feedback, every regulator should incorporate an internal model to realize dynamic compensation. Hence, internal model design plays a key role in nonlinear regulator synthesis. It should not only define a steady-state generator, understood as a substitutional model of the system to be regulated, but also facilitate relevant stabilization of the augmented system, composed of the plant dynamics and designed internal model.
The purpose of this pre-conference workshop is to provide an overview of the current status and ongoing research in the field of nonlinear output regulation with a focus on the internal model approach. It introduces recent developments on emerging nonlinear internal model design techniques and applications to global robust output regulation problems. Particularly, it provides a novel analysis on output regulation with nonlinear or uncertain exosystems. It ultimately explores interesting solutions to heterogeneous multi-agent systems control via cooperative output regulation design.
The materials in this tutorial are mainly based on research outcomes on nonlinear output regulation and applications by the authors and their collaborators in recent years.

Catheter Operating Systems with Force Feedback for Medical Applications

Abstract:
Remote-controlled vascular interventional robots (RVIRs) are being developed to increase the accuracy of surgical operations and reduce the number of occupational risks sustained by intervening physicians, such as radiation exposure and chronic neck/back pain. However, complex control of the RVIRs improves the doctor’s operation difficulty and reduces the operation efficiency. Furthermore, incomplete sterilization of the RVIRs will increase the risk of infection, or even cause medical accidents.
Our project aims at the development of a novel Catheter Operating Systems with Force Feedback for Medical Applications. The results illustrated that the proposed RVIR has better performance compared with the previous prototype, and preliminarily demonstrated that the proposed RVIR has good safety and reliability and can be used in clinical surgeries. This presentation describes the basic research concepts and some new results in our big project.

Abstract:
Long-term disabilities of the upper limb affect millions of stroke survivors. This disease mainly causes the loss of limb motion function and related complications, which makes most patients unable to take care of themselves. It not only causes great physical and psychological pressure, but also brings heavy burden to patients’ families and society. A novel upper limb rehabilitation robotic training system are being developed to help patients with upper limb and hand function training.
Our project aims at the development of a novel upper limb rehabilitation robotic training system. The results illustrated that the proposed upper limb rehabilitation robotic training system has better performance, and preliminarily demonstrated that the proposed upper limb rehabilitation robotic training system has good safety and reliability and can be used in rehabilitaion training of upper limb and hand. This presentation describes the basic research concepts and some new results in our project.
