Welcome to “System Dynamics and Controls,” 1e by Dr. S. Graham Kelly — a new first edition and comprehensive guide to understanding and controlling interdisciplinary engineering systems. The goal of this text is to provide the reader with a general understanding of how to mathematically model a linear engineering system and how to control it effectively.
The fundamentals
Engineering is inherently interdisciplinary, and successful engineers often navigate and work in multi-disciplinary teams. Whether you’re a mechanical engineer learning about electrical systems or an electrical engineer diving into chemical processes, understanding diverse disciplines is key. All engineers should have some familiarity with the modeling of physical systems of any kind, as well as with the time-dependent responses of these systems. This knowledge isn’t just theoretical, it’s integral to designing control systems that guide these systems’ operations.
Take robotics, for example. Designing a robot requires expertise in both mechanical and electrical systems. A control system for the robot, usually an electrical controller, is designed to make the robot respond appropriately to certain inputs.
The prerequisites
Before diving in, it’s important to come prepared. This text is meant for those with a background in:
- Single-variable calculus, including ordinary differential equations
- Engineering physics, with a focus on mechanics, electromagnetism, and thermal systems
- Core concepts from statics and dynamics, especially rigid body dynamics in planar motion
For more advanced sections, knowledge of multi-variable calculus will be helpful. Additionally, while not essential, prior or concurrent study in chemistry, circuit analysis, fluid mechanics, and thermodynamics will enrich your understanding of specific topics and examples.
MATLAB and Simulink
This text frequently uses MATLAB as a tool for the determination of the response of a dynamic system. MATLAB is used as a computational tool, a programming tool, and a graphical tool. From determining dynamic system responses to programming and graphical analysis, MATLAB is used extensively throughout the text. Some specific applications include:
- The Symbolic Toolbox, for tasks like inverse Laplace transforms
- The Control Systems Toolbox, for developing Bode and Nyquist diagrams
Simulink, a MATLAB-developed simulation and modeling tool, is also integrated throughout this text. Simulink allows development of models, using either the transfer function or the state-space formulation, without the programming required for MATLAB.
This text’s comprehensive approach, combining theory with practical tools like MATLAB and Simulink, equips students to tackle the complexities of interdisciplinary engineering systems.
