Description

Continuous System Simulation describes systematically and methodically how mathematical models of dynamic systems, usually described by sets of either ordinary or partial differential equations possibly coupled with algebraic equations, can be simulated on a digital computer.

Modern modeling and simulation environments relieve the occasional user from having to understand how simulation really works. Once a mathematical model of a process has been formulated, the modeling and simulation environment compiles and simulates the model, and curves of result trajectories appear magically on the user’s screen. Yet, magic has a tendency to fail, and it is then that the user must understand what went wrong, and why the model could not be simulated as expected.

Continuous System Simulation is written by engineers for engineers, introducing the partly symbolical and partly numerical algorithms that drive the process of simulation in terms that are familiar to simulation practitioners with an engineering background, and yet, the text is rigorous in its approach and comprehensive in its coverage, providing the reader with a thorough and detailed understanding of the mechanisms that govern the simulation of dynamical systems.

Continuous System Simulation is a highly software-oriented text, based on MATLAB. Homework problems, suggestions for term project, and open research questions conclude every chapter to deepen the understanding of the student and increase his or her motivation.

Continuous System Simulation is the first text of its kind that has been written for an engineering audience primarily. Yet due to the depth and breadth of its coverage, the book will also be highly useful for readers with a mathematics background. The book has been designed to accompany senior and graduate students enrolled in a simulation class, but it may also serve as a reference and self-study guide for modeling and simulation practitioners.

描述

《連續系統模擬》系統地和有方法地描述了如何在數位電腦上模擬動態系統的數學模型。這些模型通常由一組常微分方程或偏微分方程以及代數方程組組成。

現代建模和模擬環境使偶爾使用者不需要理解模擬的運作原理。一旦一個過程的數學模型被制定出來,建模和模擬環境會編譯和模擬模型,結果軌跡的曲線就會神奇地出現在使用者的屏幕上。然而,神奇有時會失靈,這時使用者必須理解出了什麼問題,為什麼模型無法按預期進行模擬。

《連續系統模擬》是由工程師為工程師撰寫的,以熟悉工程背景的模擬實踐者為對象,介紹了部分符號和部分數值算法,這些算法驅動著模擬過程。然而,該書在方法上嚴謹且內容全面,為讀者提供了對控制動態系統模擬機制的深入和詳細的理解。

《連續系統模擬》是一本高度軟件導向的教材,基於MATLAB。每章結束時都有作業問題、期末專題建議和開放性研究問題,以加深學生對模擬的理解並提高他們的動力。

《連續系統模擬》是首本主要針對工程師讀者撰寫的教材。然而,由於其廣泛的內容和深度,該書對具有數學背景的讀者也非常有用。該書旨在配合修讀模擬課程的高年級和研究生學生使用,但也可以作為建模和模擬實踐者的參考和自學指南。
