·         Diverse examples and profound problem treatment enable the reader to animate complex dynamical problems
m-files, Simulink models, VRML files and jpegs available for download provide full solutions for the end-of-chapter problems

Virtual Reality and Animation for MATLAB® and Simulink® Users demonstrates the simulation and animation of physical systems using the MATLAB® Virtual Reality Toolbox (virtual models are created in V-Realm Builder). The book is divided into two parts; the first addresses MATLAB® and the second Simulink®. The presentation is problem-based with each chapter teaching the reader a group of essential principles in the context of a step-by-step solution to a particular issue. Examples of the systems covered include mass-spring-dampers, a crank-slider mechanism and a moving vehicle. The examples are given in ascending level of difficulty and contain MATLAB®/Simulink® codes deliberately simplified so that readers can focus on:
• understanding how to link a 3-d virtual scene to MATLAB®/Simulink®; and
• manipulating the 3-d virtual scene in MATLAB®/Simulink®.
When studied in sequence, the chapters of this text form a coherent whole enabling the reader to gain a thorough expertise in virtual simulation and animation of dynamical models using MATLAB®/Simulink®. Individual chapters stand on their own, however, so that readers interested in a particular system can concentrate on it easily. Problemsare provided in each chapter to give practice in the techniques demonstrated and to extend the range of the systems studied, for example, into the control sphere. Solution code for these problems can be downloaded from insert URL.
Whether modeling the dynamics of a simple pendulum, a robot arm or a moving car, animation of a dynamical model can enliven and encourage understanding of mechanical systems and thus contribute to control design. Virtual Reality and Animation for MATLAB® and Simulink® Users will be instructive and interesting to anyone, researcher or student, working with the dynamics of physical systems. Readers are assumed to have some familiarity with MATLAB®.

 

Doctor Khaled’s Ph.D. thesis dealt with guidance and control of under-actuated ships. He modeled the dynamics of the ship under various environmental conditions in Simulink. Furthermore, he designed a patent-protected guidance system for autonomous operation of under-actuated ships. Then, he coupled the guidance system with a set of robust controllers to assess the overall performance of the system. To simplify debugging the full dynamic model of the ship and its interaction with wave, wind and current, he animated the system in Virtual Reality. Moreover, he captured these animations as video files which helped him in explaining the complex model of the ship, the randomness of the waves, the robustness of the coupled system of controllers and the guidance system to the audience of various conferences in which he presented his work. He also taught several linear control courses and used the Virtual Reality as a tool to illustrate the various applications of automatic control. Currently, He works in Cummins as a senior controls and diagnostics research engineer. He uses Virtual Reality to animate the dynamics of certain systems and actuators and these animations serve as demonstration videos for the systems.
