University, DeKalb, Illinois, USA.
E-mail :

This one-day workshop is designed to give a comprehensive and condensed overview of of the state-of-the-art computational methods and the associated software for control systems design and analysis. A special emphasis will be given to implementations of algorithms using existing softwares. If facilities are available, demonstrations using MATLAB-based control toolboxes will be given during the workshop. Mathematical and computational jargon which are often distractive to engineers will be kept to a minimum, and numerical linear algebra background which are absolutely necessary to understand material of the workshop will be presented at the workshop itself in a conceptual way, but giving the details of software and implementational issues. The workshop will be of interests to a wide variety of audience ranging from post-graduate students and faculty, to practicing engineers and researchers working on control applications, including aerospace, automotive, biology, medicine, spacesciences, structural and manufacturing engineering, robotics, and many others. In particular, the workshop will provide motivation and practical guidance to faculty desirous of including some state-of-the-art computational techniques in their existing systems theory and control courses and /or designing an exclusive graduate level course on this topic. The detailed lecture notes will be provided to the participants at the workshop.

Interval analysis and its application to parameter identification, state estimation and control

organized by
Michel Kieffer and Eric Walter
Laboratoire des Signaux et Systemes, CNRS – Supelec – Univ Paris-Sud
F - 91192 Gif-sur-Yvette

Outline of the workshop
Interval analysis (IA) is based on the very simple idea of enclosing real numbers in intervals on which computations can be carried out. Outward rounding of real intervals to the smallest computer-representable intervals and the fundamental notions of inclusion functions and contractors make it possible to obtain guaranteed results via floating-point computations, a task still believed by many to be out of reach. IA may, for instance, be used to locate all optimizers of non-convex cost functions or to prove that a given problem has no solution. It has thus countless potential applications in parameter identification, state estimation and control.

The workshop will consist of six talks of about one hour each. It will aim at a balanced presentation of concepts, algorithms, implementations and applications. Live demos will be presented and open-source software will be made available to the participants. The ability of the approach to solve nontrivial estimation and control problems will be demonstrated, and new topics for research will be suggested.

Modeling and Control of AC Machines

Organizer Presenter : John Chiasson
EE Department MS 2075
Boise State University
Boise Idaho 83725

Although electric machines have been in existence for well over a hundred years, they continue to be of increasing importance to engineers. For example, the growth in hybrid electric vehicles (often using permanent magnet synchronous machines) and wind power generation (typically using induction machines) are just two emerging technologies. This workshop is intended to be an exposition of the modeling and control of alternating current (AC) electric machines. Specifically, the induction motor, the permanent magnet (PM) synchronous motor, and the trapezoidal back-emf (BLDC) motor are all presented.

Intended Audience: Engineers who want to understand the differential equation models of AC electric machines and how they are used to develop high-performance nonlinear control algorithms.

Goals: The particular goals of this workshop are to
  1. Derive the nonlinear differential equation models of the various AC motors.
  2. Use the differential equation models to develop the nonlinear feedback control methods that achieve high-performance, i.e., provide rapid and precise control of position/speed/torque.
  3. Give experimental results of the control techniques to show their capability for high-performance.
Prerequisites: This workshop is intended for a controls audience, that is, it is assumed the audience is familiar with basic notions of feedback control. However, it is not assumed that the audience has any background in electric machines; only a basic undergraduate calculus-based physics course in electricity and magnetism.

  • Background: Magnetic Force Law, Faraday's Law, and DC Machines
  • Rotating Magnetic Fields
  • The Physics of AC Machines
  • Mathematical Models of AC Machines
  • High-Performance Control of AC Machines
  • Trapezoidal Back-EMF Machines (BLDC Machines)

Short Biography of John Chiasson
Dr. Chiasson is an associate professor of electrical and computer engineering at Boise State University in Boise Idaho USA. He has worked in the area of high-performance control of electric machines for over 15 years and has over 120 refereed publications including more than 35 journal publications in the area of electric machines. He has recently published the graduate level textbook Modeling and High-Performance Control of Electric Machines, John Wiley & Sons, 736 pages, March 2005.
