Engineering

For courses in Control Theory, in departments of Mechanical Engineering, Aerospace Engineering, or Electrical Engineering.

Reorganized for use in any length course, this introductory text provides an in-depth, comprehensive treatment of a collection of classical and state-space approaches to control system design. It ties the methods together so that a designer is able to pick the method that best fits the problem at hand. The authors provide case studies and comprehensive examples with close integration of MATLAB throughout.

• An early, understandable introduction to Digital Control (Ch. 4) – Taught via examples in Chapters 5, 6, and 7.

- Shows students how control systems are being implemented in most cases today.

- Shows instructors a path to teaching the modern implementation at an undergraduate level course.

• Close MATLAB/SIMULINK integration throughout –  Illustrates how calculations are made as the concepts are introduced.

• Detailed examples for Internal Model Principle in Ch. 7.

• Chapter-end study problems – Includes answers at the back of the book.

• Comprehensive case studies – Illustrates real-world problems and applies techniques from earlier chapters.

– Brings together the classical and state-space techniques with discussions of the relative strengths and their role in design.

• Extensive examples throughout

• Greater readability and ease of use than the previous edition.

• Greater flexibility for different types of courses:

– Reading assignments are more easily given for shorter courses that cover the basics of control.

– More advanced material is provided for longer course sequences or curious students. 

• Clearly marked problems – Indicate which section they are drawn from for easier reference.

• More logical presentation of a control engineer’s approach to key problems in Ch. 4 (such as rejection of disturbances, improvement in steady-state errors, and better dynamic response) – Compares the performance of the feedback structure to that of open-loop control:

– Begins with general equations of feedback and open-loop

structures, and follows with the performance comparisons.

– Moves non-linear material to Chapter 9, and other interesting enrichment material to the end of chapter 4 where it is less distracting to a student.

– Makes chapter easier to read and gives better support to subsequent material.

• Reorganization of selected material (often more advanced, enrichment content) – Helps instructors assign basic material more easily and makes text easier to use.
– More detailed and less common aspects of dynamic modeling moved to the end of Ch. 2.

– State variable description material moved to Ch. 7.

– Nonlinear material moved to chapter 9.

– State-space material in Ch. 3 moved to Ch. 7.

– Mason's rule moved to a starred section at the end of Ch. 3. 

– Elimination of the example of the derivation of transfer function from time-domain in Ch. 3.

– Material on Lyapunov stability in Ch. 7 moved to Ch. 9.

– Removal of the tape drive case study from Ch. 10.

• Extensively revised chapter on Digital Control (Ch. 8) – Reorganized to allow a quick introduction to digital control. 

– Instructor can now assign the first five sections to enable students to design a digital controller. 

– More advanced design techniques that handle slow sampling are contained in the last two optional sections.
