Learning of Nonlinear Control System Using -'nonlintool'

Abstract

This paper presents MATLAB based Graphical User Interface (GUI) tool, 'nonlintool'. The tool is useful for learning of analysis and design procedures of nonlinear control system. The tool offers user friendly computational platform for nonlinear control system comprises of almost all type of nonlinearities. It aims to provide quick and effective means of learning of nonlinear system. Popular methods for stability investigation of nonlinear system like- Describing Function (DF) and Phase Plane Trajectory (PPT) are covered in the proposed tool. Several relevant examples of analysis and design of nonlinear control systems are presented to demonstrate capability of the tool.
