Description

Control Systems Engineering, 7th Edition has become the top selling text for this course. It takes a practical approach, presenting clear and complete explanations. Real world examples demonstrate the analysis and design process, while helpful skill assessment exercises, numerous in-chapter examples, review  questions and problems reinforce key concepts. A new progressive problem, a solar energy  parabolic trough collector, is featured at the end of each chapter. This edition also includes  Hardware Interface Laboratory experiments for use on the MyDAQ platform from National Instruments. A tutorial for MyDAQ is included as Appendix D.

New To This Edition

  • 20% new end-of-chapter problems that highlight biomedical, robotics, or other engineering applications, including a new progressive analysis and design problem – a solar energy parabolic trough collector.
  • Greater emphasis on computer-aided analysis and design, including MATLAB®, LabVIEW®, and Simulink®. Simulink® has been updated to Simulink 8.1 and a new section has been added: Using Simulink for control system design.
  • Hardware Interface Laboratory experiments have been added to certain chapters. These experiments use National Instrument’s myDAQ® to interface your computer to actual hardware to test control system principles in the real-world.

The Wiley Advantage

  • Accessibly written. Nise is noted for his clear writing and accessible presentation.
  • Design Emphasis. Students are encouraged to go beyond a plug-and-chug approach through the use of design problems, progressive analysis and design problems, and examples and problems related to the case studies.
  • Real-world case studies. The case studies (an autonomous submersible vehicle and an antenna position control system) are built up gradually throughout the chapters to demonstrate the analysis and design process.
  • Strong learning-by-example pedagogical approach. Skill-assessment exercises demonstrate step-by-step techniques to solve most problems; cyber exploration labs show how to apply popular software tools (MATLAB®, LabVIEW®, and Simulink) to control engineering problems.
  • Clearly ties mathematics to physical reality.  Students can comprehend how theoretical concepts connect to actual system dynamics.
