The book introduces possibly the most compact, simple and
physically understandable tool that can describe, explain, predict
and design the widest set of phenomena in time-variant and
nonlinear oscillations. The phenomena described include parametric
resonances, combined resonances, instability of forced
oscillations, synchronization, distributed parameter oscillation
and flatter, parametric oscillation control, robustness of
oscillations and many others. Although the realm of nonlinear
oscillations is enormous, the book relies on the concept of minimum
knowledge for maximum understanding. This unique tool is the method
of stationarization, or one frequency approximation of parametric
resonance problem analysis in linear time-variant dynamic systems.
The book shows how this can explain periodic motion stability in
stationary nonlinear dynamic systems, and reveals the link between
the harmonic stationarization coefficients and describing
functions. As such, the book speaks the language of control:
transfer functions, frequency response, Nyquist plot, stability
margins, etc. An understanding of the physics of stability loss is
the basis for the design of new oscillation control methods for,
several of which are presented in the book. These and all the other
findings are illustrated by numerical examples, which can be easily
reproduced by readers equipped with a basic simulation package like
MATLAB with Simulink. The book offers a simple tool for all those
travelling through the world of oscillations, helping them discover
its hidden beauty. Researchers can use the method to uncover
unknown aspects, and as a reference to compare it with other, for
example, abstract mathematical means. Further, it provides
engineers with a minimalistic but powerful instrument based on
physically measurable variables to analyze and design oscillatory
systems.
