Control Engineering: An Introduction

This book introduces the subject of control engineering in a modern way. It is suitable as literature for a basic course in control engineering . It covers traditional methods based on - The Laplace transform - State space descriptions - Frequency descriptions At the beginning of the book, the focus is on simple design methods such as lambda-tuning of PID controllers and other controllers with an internal model. Possibilities and limitations for these methods are discussed in detail. More advanced design methods based on pole placement, state feedback, and state estimation as well as loop shaping in the frequency domain are also discussed thoroughly in later parts of the book. The book also treats digital implementation of controllers at an early stage. Nonlinear phenomena are discussed, but the focus is on linear descriptions. As is traditional, mainly finite-dimensional linear systems are discussed, but where possible, generalizations have also been made to infinite-dimensional systems. This means that systems with time delays are treated in a rigorous way. Fundamental limitations in control are discussed separately in a concluding chapter. The book also contains an introduction to reinforcement learning.
