• Automatic steering control of unmanned vehicles 

      Koumboulis, F. N.; Skarpetis, M. G. (2000)
      The problem of robust automatic steering of an autonomous unmanned vehicle is studied. The problem is solved using a robust P-D feedback controller feeding back the path error and the front steering angle. The design goal ...
    • Command following and disturbance rejection for drillstring systems 

      Skarpetis, M. G.; Koumboulis, F. N.; Ladopoulos, T. (2000)
      In this paper a P-D state feedback law is proposed to control the angular velocity of the bit of an drillstring system. The design objective is: the angular velocity of the bit to follow a desired signal independently from ...
    • Disturbance decoupling of singular systems via P-D feedback 

      Koumboulis, F. N.; Mertzios, B. G. (1999)
      The problem of disturbance decoupling of singular systems via proportional plus derivative (P-D) feedback is solved. The necessary and sufficient condition for the problem to be solvable is established as a rank condition ...
    • Multi - Objective robust control for 4WS cars 

      Skarpetis, M. G.; Koumboulis, F. N. (2000)
      The problem of robust regional stabilization with simultaneous robust triangular decoupling (RRSRTD) for a four wheel steering car (4WS) is studied. First the robust triangular technique is applied to the 4WS car in order ...
