Abstract:In recent years, the increasing interest and requirements for
improved engine diagnostics and control have led to the research and
implementation of advanced techniques in sensors and optimal design
approaches. In order to optimize the performance and emission of an
engine, in-depth knowledge of the combustion process inside the
engine cylinder is required. Accordingly, the torque generated by
each combustion event in the internal combustion engine is one of
the most important variables related to the combustion process and
engine performance. Due to this demand, the sensor technology has
advanced in this area recently.
To fully utilise the valuable contribution from sensor techniques
especially an innovative torque sensor, corresponding engine control
algorithms have to be developed. The engine control technologies
currently available from the mark are designed in a very
conservative way in order to ensure safety and robustness. However,
such approach has sacrifices the peak efficiency of the engine
within the safety margin of operation.
This PhD project investigates into online and off line optimization
for engine control. The objective of the research is to have
continuos real time engine tuning while maintaining sufficient
safety and robustness. A framework of online engine optimisation
algorithm will be presented in the seminar. The framework algorithm
can be used to develop an engine controller to optimise the engine
operation under all operating conditions in real time.
