Errata
A full list of errata including page and line numbers is maintained on the errata page. The following errata have been identified in this version of the text (for a listing in page order, see version 2.10a errata):
- Errata: In Example 5.5 and 5.6, m1 and m2 should be m
- Errata: Equation (5.15) is linear in the initial conditions and *input*
- Errata: In Example 5.8, the third nodal equation should be deleted
- Errata: The labels for v2 and v3 are misplaced in Figure 5.12
- Errata: Missing factor of A in second term of equation (5.26)
- Errata: In the last paragraph of Section 7.1, "reachable" should be replaced by "observable"
- Errata: In Example 7.2, the observer gain is given by equation (7.11)
- Errata: In Example 7.4, hats are missing in displayed equation for u
- Errata: Minus sign is missing in gain scheduled feedback

- Errata: Missing parenthesis in exponential for output signal
- Errata: In description of Bode plot for second order transfer function, 'a' should be omega 0
- Errata: In Example 8.8, explanation of effects of poles and zeros is incorrect and confusing
- Errata: In Example 8.9, the expression for sigma is not correct
- Errata: Before Example 9.3, range of theta should be -pi/2 to pi/2
- Errata: Missing factor of 2 pi in residue formula for proof of Theorem 9.3
- Errata: Bennett's books on the history of control were published in 1979 and 1993
Note that errata in later versions of the text may also apply to this version. A full list of errata in all versions of the text is maintained on the errata page.
