Abstract: The objective of this development forum is to provide a platform for researchers and practicing engineers to exchange their results and ideas on topics closely related to an important, yet less explored, field of finite/fixed/prescribed-time control of nonlinear and multi-agent systems. It will also provide an opportunity to younger graduate students to identify open problems for their research and interact with active researchers in this field.

Achieving stability by means of feedback for dynamical systems is a fundamentally important issue in control theory and control engineering. This development forum will look at a special type of stability: finite-time stability, that requires the solutions of the system in question to converge to an equilibrium point of interest in finite time T and stay there afterwards. This is a much stronger, and sometimes more practically desirable, property than the conventional notion of asymptotic stability that asks the solutions to converge to the equilibrium point as time t goes to infinity. Other variants of finite-time stability are fixed-time and prescribed-time stability. For fixed-time stability, the terminal time T admits a uniform upper-bound, while, for prescribed-time stability, the terminal time T is prescribed and is independent of initial conditions. In many applications such as the multi-agent rendezvous, ABS braking, missile tactical guidance, ensuring fixed/finite/prescribed-time stability for the concerned dynamical control system is highly desired.

Title: Finite-Time Mechanisms in Distributed Optimization and Formation Control

Abstract: Recently there have been significant developments in finite-time control and finite-time mechanisms in control and related applications. Finite-time control methods ensure the convergence of controlled variables in finite-time, and hence it is very appealing to various applications. Zhengtao Ding’s research group in Manchester has been involved in the development and application of finite-time control algorithms for consensus control, formation control of robots and distributed optimization for power dispatch and applications. In this presentation, some details of their involvements will be presented, in particular, in the areas of finite-time formation control and application of formation control to power systems.

Title: Prescribed-Time Control of Uncertain Nonlinear Systems via Nonsmooth Feedback

Abstract: This Talk addresses the nonsingular prescribed-time control of uncertain nonlinear systems over the infinite horizon. For this aim, as the extension of the classic finite time stability theorem, a kind of prescribed-time stability theorem is presented. By using such theorem and suitably introducing a novel prescribed-time adjustment (PTA) function into the virtual (actual) controllers, a nonsingular state feedback design is presented to drive the system states convergent to the destination within any prescribed time and stay thereafter. As a result, the nonsmooth feedback design approach to study prescribed-time control over the infinite horizon of nonlinear systems is successfully proposed. Due to the established direct connection of prescribed-time stability and finite time stability, this approach can ensure the natural extension from finite-time control to prescribed-time control by introducing the appropriate PTA function.

Title: Nonsmooth Control Methods for Mechatronic Systems and Their Application

Abstract: For mechatronic systems, there are nonlinearities, uncertain parameters, parameter variations, external disturbances which greatly influence the closed loop performances of mechatronic systems. Nonsmooth observer and nonsmooth control methods provide a different solution. These methods can effectively improve the precision as well as the disturbance rejection ability of closed-loop system. Some new research developments and results on this topic will be introduced. Considering the characteristics of motion control, flight control, multi-agent systems, several kinds of nonsmooth control design schemes are presented with experimental verification results.

Title: A Lyapunov-Based Small-Gain Theorem for a Network of Finite-Time Input-to-State Stable Systems

Abstract: This talk presents a Lyapunov formulation of the small-gain theorem for the finite-time input-to-state stability (FTISS) of a large-scale system composed of FTISS subsystems. In addition, an FTISS-Lyapunov function for the entire network system is constructed from the FTISS-Lyapunov functions of the subsystems. With respect to the previously developed nonlinear, Lyapunov-based small-gain theorem restricted to input-to-state stability, a new power-function-based scaling technique is proposed to deal with the challenge that a nonlinearly scaled FTISS-Lyapunov function may not retain a decreasing rate as a power function with a positive power less than one.

Title: Output-Feedback Finite-Time Stabilization for Nonlinear systems

Abstract: The problem of global finite-time stabilization of a broad class of lower-triangular nonlinear systems is investigated in this paper. In the present literature of finite-time control, the system dynamics were assumed to satisfy very restrictive conditions. By adopting compensation and switching control method, we propose novel solutions to solve semi-global and global output-feedback finite-time stabilization problem for a large class of systems under milder conditions. We also develop a novel analytic method to prove the semi-global and global finite-time stability of the closed-loop systems.
