Nonlinear system - Wikipedia
网页In mathematics and science, a nonlinear system (or a non-linear system) is a system in which the change of the output is not proportional to the change of the input. [1][2] Nonlinear problems are of interest to engineers, biologists, [3][4][5] physicists, [6][7] mathematicians, and many other scientists since most systems are inherently ...

Introduction to Nonlinear Systems Modelling and Control
网页2020年5月20日 · Nonlinear models may be classified into smooth and non-smooth cases. A smooth function has continuous derivatives. Non-smooth nonlinearities include backlash, hysteresis, deadband, saturation and dry-friction that arise naturally in devices. Non-smooth nonlinearities may also be introduced by hard limits such as on a power converter output ...
