Engine Systems
Scope:
- Introduction to state-of-the-art and future engine systems and their electronic controls
- Physically based mathematical models for components and subsystems, e.g., mixture formation, load control, superchargers, emission formation
- Case studies on model-based control design for optimized fuel consumption and emissions
- Team project on the IDSC engine test bench (design of an idle speed control system)
Goals:
- Understanding of the working principles of modern internal combustion engines
- Ability to describe modern internal combustion engines quantitatively with dynamic models
- Application of modern system optimization and control tools to real internal combustion engines
Lecture Material
All lecture material and communication during the semester will be published on Moodle.
Requirements
Knowledge of System Modeling, Control Systems I and II or similar courses.
There will be two different types of exercises:
Several Theory Sheets:
You recieve questions where the theory covered in the lecture has to be applied.
Two Real-world Matlab/Simulink Exercises:
- An intake manifold is modeled in Matlab Simulink. This model is used for a parameter identification using measurements on a real engine.
- A complete engine is to be modeled in Matlab Simulink. This model is used for a parameter identification and to design a model-based idle-speed controller which will be used on a real engine.There will be a competition at the end of the semester.
You will sign in for a group in the first exercise class. We recommend that at least two members of each team have experience in Matlab and Simulink. An introduction on the exercises will be given in the first exercise class.
A special lecture covering the basics of Modeling and Control will be held in one of the first exercise classes or at a date that will be announced in the first exercise class.
Additional Information
Exam
There is an oral final exam during the examination session, which covers all material taught during the course, i.e. the material presented during the lectures and exercises. Additionally, there will be a test-bench exercise, which is an optional learning task during the semester. It requires the student to understand and apply the lecture material. It contributes a maximum of 0.25 grade points to the final grade, but only if it helps to improve the final grade.
Repetition
The final exam can be repeated in the summer session, but taking the course again is recommended.
