Title: Asymptotic Full Actuation Control with Applications to Control of Autonomous Vehicle Platoons


Abstract: The rise of the full actuation control represents a holistic approach to nonlinear feedback control systems. Motivated by the pioneering work of Duanin his series of papers, we study asymptotic full actuation control for a class of commonly seen nonlinear systems, involving unknown and uncertain parameters. We will present several results, including:

  • Proposal of innovative adaptive control laws that achieve both asymptotic stability and asymptotic output regulation for the uncertain nonlinear feedback system,

  • Asymptotic linearization for uncertain nonlinear systems, based on the proposed adaptive control laws and aided by secondary least-squares estimators,

  • Asymptotic string stability for control of autonomous vehicle platoons, achieving not only the velocity consensus but also the required spacing between the neighboring vehicles.

We will also present our views on future challenges to the full actuation control and how these challenges can be tackled in the near future.

Title: Weak disturbance decoupling of high-order fully actuated nonlinear systems


Abstract: It is well known that all practical control systems are subject to external disturbances. Therefore, a feedback controller should be designed so that the closed-loop system has some desiredpropertiessuch as stability, good tracking performance, at the same time, the impact of external disturbances on the performance of the closed-loop system is attenuated to some degree.Onthe other hand, almost all models for real fully actuated systems, which are derived based on the physical laws are described by a set of high order differential equations. The traditional method for controlling these fully actuated systems is to convert the high order differential equations to the first order differential equations, which are called the state equation, and then to design feedback controllers by using the state-space design methods. Such conversion causes some inconveniences. To overcome such inconveniences, a high-order fully actuated (HOFA) design method has been proposed to controlHOFA systems. The main goal of this paper is to design a weak disturbance decoupling controller for HOFA nonlinear systems to guarantee the stability and desired output tracking performance of the closed-loop system and to attenuate the impact of disturbances.

Title:Fully Actuated System Approach for Control-Results Overview and Further Problems


Abstract: State-space models are convenient for solving out the state vectors (including their estimates and their infinite-time behaviour), but are not for the control vectors. Consequently, from the mid 1990, the state-space approach has encountered great difficulties when control of nonlinear systems was brought up. Apparently, there is no doubt that a model from which the control vector can be explicitly solved out would best perform the control. To solve a control problem, such a model for control is much more preferred to a state-space one. Inspired by the practical mechanical fully actuated systems, a type ofextended FAS models are established, from which the control vectors can indeed be explicitly solved out. Eventually, a FAS approach, which is parallel to the well-known state-space one, has been proposed for general dynamical control system analysis and designs. The FAS approach has found its great power in dealing with control of complicated nonlinear dynamical systems, including time-varying nonlinear systems with time-varying delays, constrained systems and complex nonholonomic systems. In this talk, reported results on analysis and design of control systems based on FAS approach are firstly reviewed, and new directions and problems related to control systems analysis and designs using FAS approach are also outlined.
