 |  | Control EngineeringIn the 1980s, Professor Keith Glover and his collaborators established 
        a mathematical formulation of this problem at a time of intense international 
        activity in this area. The underlying mathematics came from the field 
        of operator theory and in combination with new developments in control 
        theory entirely new and computationally tractable solutions were derived. 
        With North American co-authors he received the prestigous IEEE Baker prize 
        for the best paper in all the 1989 journals of the IEEE for this work. 
       
         
          | The methodology, known as H-infinity, has become widely 
            used in application studies as diverse as short take off and landing 
            aircraft and gas-fired power stations. The major control systems design 
            packages are now used in industry and universities around the world. 
            Within the Department, the methods have been very successfully applied 
            in the flight control studies for the Harrier jump jet with, most 
            unusually for a University group, two sets of test flights, and in 
            automotive engine control work with the Ford Motor Company. |
