Semester: SEM2
Originating Department: Electrical and Electronic Engineering
Pre-requisites: MTH101
To develop an understanding of modeling methods on mechanical systems.

To introduce the essential principles governing the behavior of first and second order systems in the time and frequency domains, and the fundamental of feedback theory and its application on vibration control.

To develop practical skills in mechatronic systems design and carrying out and reporting upon simple experiments.

Learning outcomes 
A. model dynamic systems and know systems characteristics among mechanical, thermal, fluid, and electrical systems.

B. apply essential principles governing the behavior of first and second order systems in the time and frequency domains.

C. apply analytical methods to determine natural frequencies and mode shapes and understand the stability issues in mechanical systems.

D. design simple mechatronic systems to achieve the specified objectives on performance, cost, safety, environmental protection, etc.

Method of teaching and learning 
This module will be delivered through a combination of formal lectures and supervised laboratory sessions.

In-Class Test would be arranged in Week 8 that is used to assess students’ understanding on mechanical systems modelling and first/second order vibration systems, and

Laboratory Report needs to be submitted in Week 14, which is related to the design and analysis of simple mechatronic systems.
