s = tf('s');
G = 10/(s*(s+2));
T = feedback(G,1);
step(T)
This matches the analytical solution.
Problem 6.15 (paraphrased):
Given ( G(s)H(s) = \fracKs(s+2)(s+4) ), sketch the root locus for ( K > 0 ). Find the breakaway point and the gain at which the system becomes marginally stable.

Author: [Adapted from the works of Farid Golnaraghi & Benjamin C. Kuo] Subject: Control Systems Engineering / Cybernetics
Q: Is the solution manual for the 10th edition compatible with the international edition? A: Generally, yes. The problem sets are identical. However, page numbers and figure references may differ slightly. The equations and numerical values remain the same.
Q: Are the odd-numbered solutions available for free? A: Some publishers release odd-numbered answers in the back of the textbook. Kuo’s 10th edition does include selected answers, but they are not full solutions—just final numerical values. You still need the full manual for the derivation. s = tf('s'); G = 10/(s*(s+2)); T = feedback(G,1); step(T)
Q: How do I know if a solution manual is authentic? A: Look for the ISBN. The official instructor’s edition has ISBN 978-0470-04895-1. If a PDF does not reference this ISBN, approach with caution.
Q: Can I use the 9th edition solutions for the 10th edition? A: Only partially. The 10th edition added 30% new problems, especially in the digital control and state-space sections. For the classical control chapters (2-8), the problems overlap about 70%. However, problem numbers are often reordered.
Below is an example of how a "solid" solution paper addresses specific high-value problems. This matches the analytical solution
Benjamin C. Kuo’s work is considered a classic in the field of electrical and mechanical engineering. The 10th Edition, co-authored with Farid Golnaraghi, modernizes the text while maintaining its core focus on the analysis and design of feedback control systems.
The book covers a vast landscape of topics, including:
For many engineering students, this textbook serves as the first formal introduction to these complex interwoven concepts. The exercises at the end of each chapter are designed not just to test memory, but to force the student to synthesize mathematical tools to solve real-world stability problems.
While tempting, downloading a free, low-quality scanned PDF from file-sharing sites is risky. Beyond the obvious copyright violations, these files are notorious for:
The 10th edition includes an online chapter on describing functions and phase-plane analysis. Solving for limit cycles using describing functions is extremely sensitive to algebraic manipulation. The solution manual is practically required reading here.
