In each chapter, there are five problem types:
Exercises
Problems
Advanced Problems
Design Problems/Continuous Design Problem
Computer Problems
In total, there are over 850 problems. The abundance of problems of in-
creasing complexity gives students confidence in their problem-solving
ability as they work their way from the exercises to the design and
computer-based problems.
It is assumed that instructors (and students) have access to MATLAB,
the Control System Toolbox or the LabVIEW and MathScript. All of the
comptuer solutions in this Solution Manual were developed and tested on
a Window XP platform using MATLAB 7.3 Release 2006b and the Control
System Toolbox Version 7.1 and LabVIEW 8.2. It is not possible to verify
each solution on all the available computer platforms that are compatible
with MATLAB and LabVIEW MathScript. Please forward any incompati-
bilities you encounter with the scripts to Prof. Bishop at the email address
given below.
The authors and the staff at Prentice Hall would like to establish an
open line of communication with the instructors using Modern Control
Systems. We encourage you to contact Prentice Hall with comments and
suggestions for this and future editions.
