What will you be doing?

At TNO Powertrains, we designed a coordinated air-fuel path controller for RCCI operation in a multi-cylinder heavy-duty engine. A systematic, model-based approach is followed for the design of the multivariable RCCI controller. Using the Frequency Response Function (FRF) method, linear models are identified for the air path and for the combustion process in the individual cylinders. From timing and blend ratio (BR) sweeps, it is decided to realize the high-level control objectives by controlling CA50, IMEP, BR, exhaust manifold pressure and EGR ratio. Based on the identified models, a static decoupling G_0^(-1) is designed for the combined air-fuel system. For the decoupled system, two PI air path controllers and three next-cycle PI fuel path controllers are designed. However, open research questions and possible improvements remain.

In this internship assignment we would like to investigate following the research questions:
  • Interaction analyses of MIMO control problem based-on already available FRF measurements. 
  • Possible change of output choice, and re-design of decoupling matrix G_0^(-1).
  • MIMO control design (fast reference tracking, disturbance rejection).
And finally If time and availability allows for it:
  • Implementation and experimental validation on the RCCI test setup.

What do we require of you?

  • You have a bachelor’s degree in a relevant field, for example automotive engineering, systems and control, electrical engineering or mechanical engineering.
  • You are coursing a master in a relevant field, for example automotive engineering, systems and control, electrical engineering or mechanical engineering.
  • Knowledge in Matlab/Simulink, FRF measurements, interaction analyses, decoupling design, MIMO control design.
  • You enjoy developing innovative solutions to technically challenging problems and have the right mix of intellectual curiosity and pragmatism.

What can you expect of your work situation?

You will work together with a team of enthusiastic combustion / control engineering experts on a very relevant topic in the automotive industry. The results will be used in future combustion research developments.
