System Dynamics for Engineering Students

Engineering system dynamics focuses on deriving mathematical models based on simplified physical representations of actual systems, such as mechanical, electrical, fluid, or thermal, and on solving these models for analysis or design purposes. System Dynamics for Engineering Students: Concepts and Applications features a classical approach to system dynamics and is designed to be utilized as a one-semester system dynamics text for upper-level undergraduate students with emphasis on mechanical, aerospace, or electrical engineering. It is the first system dynamics textbook to include examples from compliant (flexible) mechanisms and micro/nano electromechanical systems (MEMS/NEMS). This new second edition has been updated to provide more balance between analytical and computational approaches; introduces additional in-text coverage of Controls; and includes numerous fully solved examples and exercises.

Klappentext

System Dynamics for Engineering Students: Concepts and Applications, Second Edition, takes a classical approach to system dynamics with a balanced treatment of mechanical, electrical and thermal-fluid systems. This is the first text to include examples from compliant mechanisms and micro/nano electromechanical systems (MEMS/NEMS). The book uses modeling and solution techniques that are familiar from other disciplines (such as ordinary differential equations) and also introduces new modeling and solution procedures, including extensive use of MATLAB and Simulink. It is designed for use as a one semester systems dynamics text for upper-level undergraduate students with emphasis on mechanical, electrical, or aerospace engineering. The book contains a large number of worked examples and end of chapter exercises that allows the reader to apply concepts to realistic engineering situations. MATLAB and Simulink are used, where appropriate, to show numerical solutions and/or to solve symbolically mathematical models too involved to be solved by hand. Wherever possible, more than one solution method is provided to enable using an algorithm that best suits various approaches to the same problem. The book also contains extensive online support materials such as advanced topics, additional exercises, m-files, and (for instructors) a solutions manual and PPT lecture slides. This text will appeal to junior and senior undergraduate students in mechanical, electrical and aerospace engineering programs.
