Activities

Automation, Control & Robotics

Jeff Pieper has interests in the design and analysis of control systems and mechatronics. Other research areas include the analysis of dynamic systems and the development of design methodologies for mechatronic systems.
Current and recent research projects include:

  • Control of wind and water turbines. Alternative energy turbine systems are challenging control problems in that they involve time varying dynamics, inherent instabilities, differing control objective under various operating conditions and other difficulties. Applications of parameter varying and adaptive control using emerging techniques have proven useful. Issues surrounding measurement of the operating point, estimation of the power output of the turbine and other practicalities make the area one of great interest.
  • Helicopter flight controller design. In this line of research, a number of problems associated with control of helicopters is explored including hover and forward flight, slung loadings, flight under degraded visual cue environments and other aspects.
  • Mechatronic systems design. General limits of performance for electro-mechanical systems are studied with a view to optimized design and use of computer-based control. The economic trade-offs associated with the inclusion of computational elements is balanced by the improved behaviour.
  • Robust control design. The search for a control design methodology that can deal with uncertain nonlinear and multivariable systems is an ongoing research problem. Within this topic various strategies are developed and tested experimentally with a view to practical application.
