Nonlinear control systems are those control systems where nonlinearity plays a significant role, either in the controlled process plant or in the controller itself. Nonlinear plants arise naturally in numerous engineering and natural systems, including mechanical and biological systems, aerospace and automotive control, industrial process control, and many others.

Last five decades witnessed remarkable developments in linear control systems and thus problems in this subject has been largely resolved. The scope of the present paper is beyond linear solutions. Modern technology demands sophisticated control laws to meet stringent design specifications thus highlighting the increasingly conspicuous position of nonlinear control systems, which is the topic of this paper. Historical role of analytical concepts in analysis and design of nonlinear control systems is briefly outlined. Recent advancements in these systems from applications perspective are examined with critical comments on associated challenges. It is anticipated that wider dissemination of this comprehensive review will stimulate more collaborations among the research community and contribute to further developments. Many physical processes are represented by nonlinear models.
Nonlinear control theory is the area of control theory which deals with systems that are nonlinear , time-variant , or both. Control theory is an interdisciplinary branch of engineering and mathematics that is concerned with the behavior of dynamical systems with inputs, and how to modify the output by changes in the input using feedback , feedforward , or signal filtering. The system to be controlled is called the " plant ". One way to make the output of a system follow a desired reference signal is to compare the output of the plant to the desired output, and provide feedback to the plant to modify the output to bring it closer to the desired output. Control theory is divided into two branches. Linear control theory applies to systems made of devices which obey the superposition principle. They are governed by linear differential equations.

This book has been prepared as a tribute to Prof. Alberto Isidori on the occasion of his 65th birthday. The book contains 27 chapters written by a number of researchers who have been involved, in different ways, in the prolific and high-impact career of Prof. The chapters cover a significant number of control and systems theory topics and describe a mix of new methodological results, advanced applications, emerging control areas and tutorial works.
- Танкадо требует, чтобы мы признали существование ТРАНСТЕКСТА. Но он несколько опоздал. Сьюзан хотела что-то сказать, но ее опередил Джабба: - Значит, Танкадо придумал шифр-убийцу.
Разница, - бормотал он себе под нос. - Разница между U235 и U238. Должно быть что-то самое простое. Техник в оперативном штабе начал отсчет: - Пять. Четыре. Три. Эта последняя цифра достигла Севильи в доли секунды.

Non-linear Control Systems We can simply define a nonlinear control system as a control system which does not follow the principle of homogeneity. In real life, all control systems are non-linear systems (linear control systems only exist in theory).
