On limit cycling control systems
A. Gelb,W.V. Velde +1 more
TL;DR: In this article, a class of limit cycling feedback control systems is investigated using a simple and practical analytic tool to determine input-output dynamic response characteristics, and the nature of the dynamic response adaptivity of such systems is shown.

A New Dual-Input Describing Function and an Application to the Stability of Forced Nonlinear Systems
J. E. Gibson,R. Sridhar +1 more
TL;DR: In this paper, a general dual input describing function (DIF) was derived for single-valued nonlinearities subjected to two arbitrary noncommensurate sine waves and applied to the problem of the stability of nonlinear systems subjected to sinusoidal forcing.

Improving Digital-to-Analog Converter Linearity by Large High-Frequency Dithering
TL;DR: A new method for reducing harmonic distortion due to element mismatch in digital-to-analog converters is described, achieved by using a large high-frequency periodic dither, which results in more than 10 dB improvement in the signal- to-noise-and-distortion ratio.

Effect of Tangential Dither Signal on Friction Induced Oscillations in an SDOF Model
TL;DR: In this paper, the authors examined how friction-induced oscillations in a traditional mass-on-a-moving-belt system are affected by highfrequency excitations, commonly referred to as dither signals.

Effects of delays on dynamics
Abstract: Part one of these lectures is devoted to two fixed point theorems motivated by dynamics in delay equations: an assymptotic fixed point theorem which can be applied to determine ω-periodic solutions of an (ω-periodically forced equation and an ejective fixed point theorem which can be applied to the determination of nontrivial periodic solutions of autonomous equations. Part two is devoted to large delays, Hopf bifurcations and fixed points of maps. Part three shows that small delays can destroy stability properties in delay differential equations as well as boundary control of partial differential equatons.
