MP3395 Mechanical Engineering Systems

Learning outcomes

 

This assignment is structured that students show evidence for partial fulfilment of the following module learning outcomes:

1) Structured and informed design and development of engineering systems through the application of scientific principles and methodology to a variety of systems

2) Apply mathematical and engineering principles as either a part or the whole of the analysis and evaluation of the performance of a variety of engineering systems and processes quantifying the limitations of the modelling

3) Apply a systems approach to engineering problems to classify, analyse and evaluate the performance of systems and components through the use of modelling techniques 

Tasks

The case study in this coursework is a micromirror (microscanner) system [2, 4-6]. To provide you with a guidance, the following tasks will help you to complete your final report.

Introduction

1. Describe the microscanner system technology. This should cover a brief history and how the system works. It may also cover fabrication methods and materials, actuation methods, application and current challenges.

2. Discuss different dynamic models of a micromirror system from the point of view of degrees of freedom and mathematical modelling.

3. Discuss various control methods used in literature to control a micromirror system including advantages and challenges, and your viewpoint

 

Simulation and Analysis

1. Create a table of numerical values (e.g. from literature or make reasonable assumptions) suitable for the design parameters for your model. Describe all your assumptions.1

2. Determine the controlled variable (output variable) and develop a model of the closed-loop control system in MATLAB SIMULINK (or any other suitable software).

3. As a control engineer, you are to design and analyse a control system for the micromirror (microscanner) system. First, you aim to investigate the performance of the open-loop system. For this, compare the time response of the micromirror to achieve three different angles, e.g., 5° , 20° , and 45°. Specify the range that the open-loop system has the best performance.
