Course Overview
All systems are inherently nonlinear in nature. This course deals with the analysis of nonlinear systems. The need for special tools to analyze nonlinear systems arises from the fact that the principle of superposition on which linear analysis is based, fails in the nonlinear case. The course exposes the students to various tools to analyze the behaviour of nonlinear systems, culminating in the stability analysis, which is of paramount importance in control systems.INTENDED AUDIENCE :PhD, MS/M. Tech/ ME, Senior Undergraduate students from EE, ME, AE, PHPRE- REQUISITES : Undergrad control engineering, basic knowledge of differential equations and linear algebra is highly desirable.SUPPORT INDUSTRY : Any robotics, space and defence related industries
