This unique, brief, interdisciplinary text uses the concept of automatic control as a unifying idea to explain the field of engineering - and the kinds of problems engineers solve - to first-year students. The author focuses on the basic principle of feedback and shows how it is used to design automatic controllers. Students learn how to develop explicit engineering models, expressed as linear differential equations with constant coefficients for each of the systems they study. Then, they will learn to solve these equations both analytically and numerically. Numerical solutions are performed using SIMULINK®. System stability and system performance are introduced, and the book concludes with a capstone project in which students use simulations and experiments to develop automatic controllers for a computer-controlled model car.
- Completely updated to MATLAB® V5, with supporting Web site.
- Uses automatic control systems as a vehicle to teach mathematical concepts (such as differential equations) in the context of real-world engineering, while introducing students to engineering design.
- Covers basic engineering concepts such as feedback, system stability, and system performance at a level appropriate for first-year students.
- MATLAB® simulations using SIMULINK® provide tangible, interactive experiments: A step-by-step procedure for building SIMULINK® block diagrams is provided.
- Concise and inexpensive enough to serve as a supplement for an Introduction to Engineering course, with the advantage of effectively integrating the use of MATLAB® into the course.
