Sinopsis
This book introduces nonlinear control systems for control engineering and science to graduate, undergraduate students and researchers; it targets control engineering students who do not like to do not have time to derive and prove mathematical results for nonlinear control systems. It can be serve as a text book for nonlinear control systems, especially for linearization techniques which is a common approach in controlling nonlinear systems. The development of computer software for nonlinear control systems has provided many benefits for teaching, research, and the development of control systems design. MATLAB is considered the dominant software platforms for linear and nonlinear control systems analysis. This book contains a MATLAB based program that helps teachers, students, and researchers with an easy to use for finding linearization controller for a specific nonlinear class of systems Chapter (1) is an introduction to theoretical aspects of nonlinear linearization techniques. We sue a simple and complex examples to better illustrate the method on how to find the linearization controller for single and multi input output systems. In section (1.9) A MATLAB based program is developed and use to find linearization control using symbolic MATLAB libraries for a special class of nonlinear systems Chapter (2), the concept of structure variable control will be introduced in intuitive way, with illustrative examples that makes the reader familiar with the theory of sliding mode control in an easy and simple way. After having defined the control law, the parameters of the controller should be identified, hence a simple method is presented to find those parameters. In section (2.4) A MATLAB based function is developed to find the sliding mode surfaces and controllers using symbolic MATLAB library for SISO and MIMO nonlinear dynamical systems that could be written in a special form. This textbook provides an easy way to learn nonlinear control systems such as linearization technique and slidng mode control (Structrue varibale control) which are one of the most used techniques in nonlinear control dynamical systems; therefore teachers-students and 2 researchers are all in need to handle such techniques; and since they are too difficult for them to handle such nonlinear controllers especially for a more complicated systems such as induction motor, satellite, and vehicles dynamical models. Thus, this document it is an excellent resource for learning the principle of linearization and sliding mode techniques in an easy and simple way: (a) Provides a briefs description of the linearization and sliding mode control strategies (b) Includes a simple method on how to determine the right and appropriate controller (P-PI-PID) for linearization control strategy. (c) Provides a MATLAB symbolic based programs that can solve the Lie derivative of any nonlinear dynamical system that could be written in a special form (d) A Symbolic Matlab Based function for finding the linearization and sliding mode controllers are developed and tested using several examples. (e) A simple method for finding the approximate sliding mode controller parameters is introduced
