This book presents an overview on the various aspects of Nonlinear Control Systems. A trend of examining Nonlinear Control Systems has been observed over the past few years. Consequently, methods for its analysis and design have improved rapidly. This book illustrates nonlinear designs like Feedback Linearization, Lyapunov Based Control, Adaptive Control, Optimal Control and Robust Control and discusses various applications which are independent of each other. The book offers information on modern control techniques and consequences which involve diverse application areas. It attempts to explain applications of these techniques to real-world systems through both simulations and experimental settings.
