Demonstrate a working knowledge of using mathematical and engineering modeling tools such as matlab and Simu link to address real world electrical and electronic engineering design challenges
Please refer to the lecture slides (introduction to Engineering Modelling and Simulations) on the six key features a real-world engineering model is expected to have.
Please refer to the real-world problem examples and the template for the ‘basic’ reflective statement provided as follows:
Advanced Real-world Engineering Design Problem (Example I) The development of a housing estate has just been recently approved by a County Borough Council in North Wales, United Kingdom. The housing estate will have only 3-bedroom bungalows and each bungalow will have a living space with ceiling-fitted lighting points.
The electrical services team responsible for the electrical works on the estate project is currently looking for cost-effective and efficient ways to estimate the total power consumption of each bungalow. In particular, the number of ceiling-fitted lighting points to be used in the living space in each of the bungalows to ensure a good level of illumination (dusk hours) and save energy as far as possible is to be estimated and justified.
As a final year engineering student. use your knowledge of engineering design. modelling, and simulation tools such as MATLAB and Simulink to determine the most cost-effective and the number of lighting points to be used and justify your choice by comparing possible alternatives.
The following data can serve as a guide for living spaces (students who address this real-world problem must provide the missing (Reference’) and other references):
The wattage of each lamp at each lighting point must be equal and it may assume any standard value, but not more than 60 W The illuminance in a standard living space may vary from 300 lux to 500 lux (Reference 7.
The numberof lighting points may vary from 2 to 4.
Typically, lighting points are connected in parallel as illustrated below for four lighting points. Series and/or series-parallel arrangement or connections may also be employed with reasonable justification.
The power consumption may be estimated by using standard electric circuit theorems and equations (all circuit laws/theorems must be clearly stated).
