This document provides a foundational overview of mechatronics, emphasizing its unique design philosophy, essential **hệ thống CĐT** modeling methodologies, and underlying principles of rigid body mechanics. Understanding these core concepts is vital for engineers seeking to innovate and optimize complex integrated systems, laying the groundwork for advanced applications and technological advancements.

Undergraduate and graduate students, researchers, and practicing engineers in Mechanical Engineering, Electrical Engineering, Computer Science, and Mechatronics seeking a foundational understanding of mechatronic system design, modeling, and rigid body mechanics.

This academic overview delves into the foundational aspects of cơ điện tử (mechatronics), an essential multidisciplinary field that integrates mechanical engineering, electronics, computer science, and information technology. It clearly delineates the **concept of Mechatronics systems**, highlighting their distinctive parallel design philosophy compared to traditional sequential approaches. The document elaborates on the **structure of Mechatronics systems**, illustrating how diverse components like information, mechanical, computer, and electrical subsystems, along with actuators, sensors, and control elements, are intricately combined. A comprehensive **quy trình thiết kế** is presented, spanning conceptualization, detailed modeling, prototyping, and deployment, emphasizing the role of **mô phỏng** throughout these stages. Furthermore, the text meticulously covers **mô hình hóa hệ thống**, defining it as the representation of system behavior through mathematical equations and logical interpretations. It differentiates between static and dynamic models, elucidating the concepts of parameters, input, and output signals. Two primary methods for model representation are explored: Text-based Programming Languages, discussing their advantages in mathematical expression but noting their drawbacks for interdisciplinary collaboration, and Block Diagram Languages, valued for their visual clarity and ease of use in representing system components and signal flows. The critical role of **simulation** in solving models and employing methods like polynomial approximation for differential equations is also addressed. Finally, the document provides a robust section on **cơ học vật rắn**, detailing fundamental principles such as force and moment, kinetic energy and work, and the crucial concept of mass center.
