hela Sverige The combustion engine is a complex multivariable system which conventionally has been controlled with separate feed-forward and feedback. However, as it is challenging to incorporate the multivariable impact in by conventional approach and there is no supporting methodology for constraint handling, a more coordinated control method is desired. Model Predictive Control (MPC) is an attractive method that can control multivariable systems and take constraints into account. It also is a flexible platform where optimization or constraints easily can be added or subtracted. To comply with the more stringent emissions regulation and improved fuel consumption on a combustion engine, the air charge and start of injection must be accurately controlled to ensure that the engine's outflow meets the aftertreatment system's needs. This work aims at calibrating the engine model and thereafter designing and implementing a nonlinear MPC to control EGR valve, intake throttle valve, waste gate and start of fuel injection.

Description of Master thesis work
Initially a literature study should be conducted in order to gain information and experience from previous work. The next steps are listed below:
Getting familiar with engine model
Calibrate base engine model using test cell data
Design and implement a nonlinear MPC using a commercial solver. Following the same SW process as for production.
Evaluate the MPC in the simulation environment. Simulate on virtual ECU (complied for Windows instead of ECU)
Potential bonus: run the nonlinear MPC on the engine in a test cell
Thesis Level: Master
Suitable background
Strong skills in control systems and preferably MPC knowledge
Proficient in MATLAB/Simulink
Basic understanding of C
Knowledge about combustion engines is a plus
Language: English
Starting date: January 2024
Number of students: 2
Tutor
Ali Ghanaati, Simualtion engineer
