|Title: Parametric Control Systems Design with Applications in Spacecraft Control
Abstract: A parametric approach for control systems design establishes a general parameterization of a set of controllers of certain type, which meet some dominant system design requirements, and meanwhile, provides all the design degrees of freedom which may be further utilized to modify some other closed-loop system performance. Due to these advantages, parametric control systems design approaches have played an important role in both theories and applications. In this talk, a general framework for a type of unified parametric approaches for control systems design is briefly introduced, which are based on general complete parametric solutions to a type of generalized Sylvester matrix equations. One of the key steps, i.e., finding the parameterization of the required type of controllers, is especially treated and emphasized.

|Title: Precision Mapping and Vehicle State Estimation for Autonomous Highway Vehicles
Abstract: Given recently publicized demonstrations of autonomous vehicles operating on public streets, various countries are considering technical, legal, and ethical issues related to their legalization. Even without fully autonomy, intelligent transportation systems have high potential for improvement of highway safety and throughput, especially after gwhere-in-laneh accuracy can be reliably achieved. This presentation will discuss the role of control and systems theoretic methods related to practical autonomous vehicle applications, particularly as they relate to automated construction of precise feature maps and reliable real-time navigation with position accuracy at the decimeter level. Both applications require reliable and automated data fusion from various sensor modalities: LIDAR, camera, global navigation satellite systems, inertial measurements, etc. The presentation will survey and present modern methods for roadway feature mapping and vehicle state estimation. Results from a demonstration at the US Department of Transportation Turner Fairbanks Research Center will be included.

|Title: Non-Contact Distance Metrology by Optical Comb for Industry and Society
Abstract: Recently, high accuracy and non-contact measurements are required for improving the products quality in industry and guarantee the safety in society. In this present, temporal coherence interferometry is developed using the optical comb which of repetition frequency is in general 100 MHz and is phase-locked to a rubidium clock standard of 10-11. Therefore, the interference fringe pattern is not fairy affected by the air turbulence and mechanical vibration. At first, fast optical comb whose repetition frequency is 15 GHz is developed using fiber Fabry-Perot etalon and so the repetition distance in space is exactly 10 mm. Then, the comb is applied to absolute distance measurement with an accuracy of 0.05 Êm. This technology has a possibility of measuring the distances up to hundreds meter. Next, it is applied for non-contact measurement of a coordinate measuring machine with 0.2 µm. This technology is also applied to the remote non-contact measurements of the huge-size objects such as airplane with a rough surface of Ra=1.6 µm.

|Title: Stable Manifold Method for Nonlinear Optimal Control
Abstract: Hamilton-Jacobi equations have been one of the serious impediments for the application of nonlinear control theory. Recently, a novel approach based on stable manifold theory for numerically solving Hamilton-Jacobi equations is developed. This approach is unique in that it obtains the derivative of the solution of Hamilton-Jacobi equations and is efficient in that it consists of successive computations which are suitable for computer implementation. We have developed a Matlab package that carries out the manifold computation and creates optimal feedback controllers. This computational package for optimal control has been applied for a number of real-world systems with experimental verifications. Those applications include pendulum swing up, aircraft control and control of mechatronic systems such as electric motors (AC and DC) and control moment gyros. In this talk, the general notion of invariant manifold of dynamical systems and its significance in nonlinear control design will be also discussed.
