Holden, Arun V., (editor), *Chaos,* Princeton University Press, Princeton, New Jersey,
1986. 324 p.

This volume set out the basic applied mathematical and numerical methods of chaotic dynamics and illustrates the wide range of phenomena, inside and outside the laboratory, that can be treated as chaotic processes. Topics include: what is the use of chaos?; a graphical zoo of strange and peculiar attractors; one-dimensional iterative maps; two-dimensional iterative maps; chaos in feedback systems; the Lorenz equations; instabilities and chaos in lasers and optical resonators; differential systems in ecology and epidemiology; oscillations and chaos in cellular metabolism and physiological systems; periodically forced nonlinear oscillators; chaotic cardiac rhythms; chaotic oscillations and bifurcations in squid giant axons; quantifying chaos with Lyapunov exponents; estimating the fractal dimensions and entropies of strange attractors; and how chaotic is the universe?

The chapter *Chaos in Feedback Systems*
by A. Mees discusses chaos in pulse-width-modulated (PWM) feedback systems
where the existence of a snap-back repeller is sufficient for chaos. The
conditions are plotted on the familiar saw-tooth amplitude-vs-time diagram.

Quote from Mees:

"For the engineer designing a feedback system, it would appear that chaos is always to be avoided: 'noisy' oscillations with little information content, or sudden unpredictable excursions of physical variables, are seldom likely to be desirable. Feedback tends to be used to stabilize systems, not to randomize them."
