Research

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 optimization techniques to complex systems.

  • H-infinity and Robust Control Methods
  • Robust Gain Scheduling LPV/LFT
  • Linear Matrix Inequalities (LMIs)
  • Flight Control Systems (Helicopter, Aircraft Autopilots, UAVs)
  • Non-linear Control (sum-of-square analysis, feedback linearization)
