Explore: Describing Function

In control systems theory, the describing function (DF) method, developed by Nikolay Mitrofanovich Krylov and Nikolay Bogoliubov in the 1930s, and extended

a transfer function (also known as system function or network function) of a system, sub-system, or component is a mathematical function that models

a theorem or an axiom asserts the existence of a function having some properties, without describing it more precisely. Often, the specification or description

input describing functions (HOSIDF) were first introduced by dr. ir. P.W.J.M. Nuij. The HOSIDFs are an extension of the sinusoidal input describing function

Bessel functions are mathematical special functions that commonly appear in problems involving wave motion, heat conduction, and other physical phenomena

of describing function, even though its applicability is disputed. In contemporary philosophy of biology, there are three major accounts of function in

In control theory, a closed-loop transfer function is a mathematical function describing the net result of the effects of a feedback control loop on the

mathematics, the trigonometric functions (also called circular functions, angle functions or goniometric functions) are real functions which relate an angle of

The gamma function then is defined in the complex plane as the analytic continuation of this integral function: it is a meromorphic function which is holomorphic

periodic function is a function that repeats its values at regular intervals. For example, the trigonometric functions, which are used to describe waves
