Development of robust adaptive and nonlinear control methodologies. Techniques will be developed that will allow industrial plants to operate with lower direct or environmental cost, and airborne vehicles to operate more efficiently or more safely.
Safe Adaptive Control. Adaptive controllers are intelligent controllers, which can redesign themselves as they learn more about the environment. There are many algorithms for adaptive controllers; some of them can cause unacceptable behaviour during the learning process. Safe adaptive controllers are those for which this behaviour is ruled out. This project is concerned with developing procedures for guaranteeing the safety property in a wide variety of situations.
Nanoindentation-induced Phase Transformations and Physical Property Changes in Semiconductors. The motivation for this study derives from recent findings of intriguing phase and structural changes induced in semiconductors under a small indenter when it is pressed into the surface.

The motivation for this study derives from recent findings of intriguing phase and structural changes induced in semiconductors under a small indenter when it is pressed into the surface. Using an array of sophisticated techniques, in this study we plan to explore for the first time the structural changes that can be induced in semiconductors on the nanoscale and to study what novel properties, particularly electrical, such nanoscale regions may have. Detailed nanoindentation studies will focus on understanding and exploiting deformation of silicon, to open up an exciting prospect: the development of an entirely new, ultra-high-density information storage process.Read moreRead less

Numerical Algorithms for Solving Convex Optimization Problems Arising in Systems and Control Theory. The need to optimize occurs frequently in engineering applications. Typically one has a set of constraints specifying what solutions are allowable or meet design specifications and one would like to choose from these allowable solutions one which is optimal with respect to some meaningful metric. Such optimization problems tend to be rather complicated and must be solved numerically.

Hybrid control systems are mathematical models of heterogeneous systems consisting of digital computer components interacting in real-time with continuous physical processes. Their many engineering applications include air traffic control, medical technology and automated transport. Motivated by such safety-critical and high-confidence applications, the project aims to develop a unified framework of mathematical logics adequate to formally represent and reason about the structure, behaviour, and properties of hybrid control systems, and use this to develop methodologies for automatically synthesising hybrid control programs that are provably correct with respect to their specifications.
