**Develops both the transfer-function model and state-variable
model** for the analysis and design of linear analog systems.

**Discusses the important concept of system stability**,
along with the Routh-Hurwitz stability criterion.

Explores modern control-system design, developing pole-placement
design and introducing the design of state estimators.

Includes coverage on such nonlinear system analysis methods
as describing-function analysis, linearization, and the state-plane
analysis.

**Introduces expanded frequency-response design criteria
early in the presentation** to help explain closed-loop systems.

Offers two Control Systems Programs (CPS) containing software
and documentation for the IBM PC and compatible computers.

**NEW--adds a section on time-scaling differential equations**,
helping students relate the transfer functions of systems examples
to those of practical systems.

**NEW--added additional practical applications**--both
as examples and end- of-chapter problems--to better relate the
mathematical developments to physical systems.

- offers entirely NEW end-of-chapter problems--all of
which lead students through a second method of the solution to verify
results.
- illustrates the computer calculation of the results of
the example with short MATLAB programs when applicable.

**Gives instructor''s maximum text/course flexibility**,
placing more advanced material towards the end of each chapter, enabling
easy topic ommission for a less intense course.
