Control system
“Control Systems are components that are added to other components, to increase functionality, or to meet a set of design criteria”
The study and design of automatic control systems, a field known as control engineering.
Branches of Control Engineering
Classical Control
Modern Control
Robust Control
Optimal Control
Adaptive Control
Non-Linear Control
Game Theory
Advantages over Open Loop
Disturbance rejection
Guaranteed performance even with model uncertainties.
Unstable process can be stabilized.
Reduced sensitivity to parameter variations.
Some cases open loop and closed loop used together.
Models
Models are used to express the characteristics of reality which are considered important and to neglect those which seem secondary.
By these simplifications, good models allow us to obtain an easily understandable, mathematically calculable image of the real world
If a model is formulated with the aid of mathematical relations, we speak of mathematical models.
This lecture deals with construction and use of mathematical models in automotive applications.
Mathematical Modelling
Is often used in place of experiments when experiments are too large, too expensive, too dangerous, or too time consuming.
Is a modern tool for scientific investigation.
Has emerged as a powerful, indispensable tool for studying a variety of problems in scientific research, product and process development, and manufacturing.
