the theory of nonlinear systems has applications to problems of population growth, economics, chemical reactions, celestial mechanics, physiology of nerves, onset of turbulence, regulation of heartbeats, electronic circuits, cryptography, secure communications and many others.
In mathematics and science, a nonlinear system is a system in which the change of the output is not proportional to the change of the input. Nonlinear problems are of interest to engineers, biologists, physicists, mathematicians, and many other scientists since most systems are inherently nonlinear in nature. Nonlinear dynamical systems, describing changes in variables over time, may appear chaotic, unpredictable, or counterintuitive, contrasting with much simpler linear.
Nonlinear systems are widely used in different industries, including chemical engineering, aerospace, electrical engineering, robotics, and biomedical engineering. These systems are used to model, analyze, and control complex processes and systems, such as chemical reactions, aircraft flight, power grids, robot motion, and biological systems. Nonlinear systems allow engineers and scientists to ensure stable and efficient performance and develop control strategies for various applications.
