Talk title: Some ‘exciting’ issues in the problem of observer design

Abstract Observer design, for nonlinear systems in particular, remains a challenging topic in control, either for the control design itself or for the related issue of monitoring for instance. Various strategies are available, depending on the type of system under consideration, but various issues are also still open. Amongproblems which are specific to dynamics that are NON linear, is the one of handling systems which are said to be NON uniformly observable, that is for which observability depends on the applied input. This leads to the notion of 'exciting inputs'. Starting with a short overview on observability and observer tools for nonlinear systems, the talk will be an opportunity to focus on this specific issue of excitation, and discuss some recent works towards solutions in that respect.

Talk title: Sampled-data and Networked Control Systems: A Time-Delay Approach

AbstractA classical approach to sampled-data control is based on discretization, which looses an information on the inter-sampling behavior and performance. To avoid the latter problem, a time-delay approach to sampled-data control was introduced, where the system was modeled as a continuous-time system with the delayed input/output. The time-delay approach became popular in networked control systems, where the plant and the controller exchange data via communication network. In the present talk three main approaches to
sampled-data control will be discussed. A recent extension of the time-delay approach to networked-control systems will be demonstrated, where variable sampling intervals, communication delays and protocol scheduling are taken into account. Also event-triggered control will be mentioned.

Talk title: Nonlinear digital Lyapunov based stabilizing control

Abstract: The expansion of digital technologies in current life renews the interest of the control community for sampled data (SD) systems. Commonly, SD dynamical systems will  refer to dynamical systems fed by sampled data and actuated through piecewise constant controls. Two preliminary assessments are first that SD systems are inherently hybrid systems and second that discrete-time (DT) control theory represents a pool of useful methodologies to handle hybrid connected dynamical structures. SD systems are in fact particular cases of DT systems which are parameterized by the sampling period. In fact, starting with a continuous-time dynamical system to be controlled in a digital environment (embedded technology), a direct  way to proceed is to sample the dynamics so that to set the problem on the DT equivalent model. The same advantage to unify  the dynamical structure to be controlled through sampling is also met when facing the control of interconnected dynamics (e.g.networked control). In conclusion, digital control at large (including discrete-time and sampled-data dynamical systems) is part of hybrid technologies.

In the talk, we will describe Lyapunov based stabilizing control methodologies for nonlinear discrete-time and sampled-data systems. Input Lyapunov matching, backstepping like and passivity based techniques will be described. In this latter case, we will refer to a novel notion of average passivity introduced for discrete-time dynamics. Exact solutions will be proposed but the focus will be set on approximate solutions  to provide elegant and easily computable solutions which preserve the performances and compensate the usual degradations met under digital implementation through zero order devices. Practical mechanical or electro mechanical examples will illustrate the topic with simulations.

Talk titleThe BigPicture: Economic plantwide control for complete processing plants.

Abstract: A chemical plant may have thousands of measurements and control loops. By the term plantwide control it is not meant the tuning and behavior of each of these loops, but rather the control philosophy of the overall plant with emphasis on the structural decisions. In practice, the control system is usually divided into several layers, separated by time scale: scheduling (weeks) , site-wide optimization (day), local optimization (hour), supervisory and economic control (minutes) and regulatory control (seconds). Such a hierchical (cascade) decomposition with layers operating on different time scale is used in the control of all real (complex) systems including  biological systems and airplanes, so the issues in this section are not limited to process control. In the talk the most important issues are discussed, especially related to the choice of ”self-optimizing” variables that provide the link the control layers.  Examples are given for optimal operation of a runner and distillation columns.
