My research interests are primarily in the areas of control and the application of convex optimisation for control system analysis and synthesis. I am interested in robust gain scheduling robust tracking fixed-order synthesis control within the Linear Matrix Inequality framework. I have a significant experience in the design of controllers for Aerospace Systems (helicopter control re-entry space vehicle control and autopilots) and more generally in the application of linear matrix optimisation techniques to complex systems.
