Professor Matthew Turner BEng, PhD, MIEEE

Teaching/Tutor Allocation (ELEC)

Matthew Turner received the BEng degree in Electrical and Electronic Engineering from the University of Surrey in 1996 and the PhD in Control Engineering from the University of Leicester in 2000. After a post-doc he continued at Leicester for several years becoming lecturer, then senior lecturer and then professor. At Leicester he served in various leadership capacities including Deputy Head of Research (Engineering) and Head of the Aerospace and Computational Engineering Research Group.  He joined the Cyber-Physical-Systems Research Group in ECS in March 2020.

Internationally, he is best known for his contributions to anti-windup control - algorithms which augment standard control systems so that they retain stability and functionality in the presence of input constaints (ubiquitous in control systems). His ideas on anti-windup have been applied to various practical control systems and, together with DLR Braunschweig, he was part of several flight test campaigns examining the efficacy of anti-windup compensators for the alleviation of pilot-induced-oscillations (PIO's) in highly augmented aircraft.

For serveal years he served as an associate editor for the International Journal of Control (under the editorship of Prof. Eric Rogers) and has served in various editorial and programme committee capacities for a number of international conferences.

Research

Research interests

Dr. Turner's research interests are currently focused on robust control, adaptive control and absolute stability analysis of nonlinear control systems, and the application of these topics to various physical systems. He has worked with various aerospace companies and institutions in the UK and elsewhere and has experience designing and implementing advanced control systems for a number of different aerospace systems. His research has been funded by both government agencies and industry. He is currently particularly interested in

  • Adaptive control systems and how they can be made robust and function in situations not originally envisaged
  • Anti-windup algorithms for systems with control signal constraints - retro fits to existing controllers to enable them to function well when actuator position/rate-limits are present
  • Absolute stabilty of systems containing static, isolated nonlinearities - especially efficient, convex algorithms for their analysis
  • The cross-over between control and artificial intelligence

Teaching

Dr. Turner currently teaches the following modules

  • ELEC3201 Robotic Systems
  • ELEC2210/2211/2219 - Vector Calculus part
  • ELEC6260 - Nonlinear Control of Aerospace Systems

Dr. Turner supervises projects in the general area of control systems, particularly, but not limited to, those pertaining to aerospace systems.
