Our research in this area focuses on investigating the motion control of electromechanical and hydraulic systems. We carry out research in adaptive and robust control of hydraulically actuated systems in many application areas.

We have applied an adaptive control strategy to the Centre’s multi-axis shaker table (MAST). This allows for improved tracking despite cross-axis interaction. We also research the control of magnetic bearing systems, which have many advantages over passive bearings, including:

  • higher operating speeds
  • no wear under normal operation
  • the ability to control rotor position and transmitted force
  • the elimination of lubrication supply systems

Research projects

Many of our current and recently completed control and actuation projects are for aerospace and automotive applications.
