Intelligent systems engineering personal statement example

Why do you want to study this course or subject?

For three years my job involved following a van driver around commercial kitchens and cold stores, changing fans, cleaning coils and reading fault codes off controllers. What stayed with me was how much of the work was information rather than metal. A chiller would trip because a sensor had drifted, or because the control logic was fighting a badly set schedule, and the repair was often a settings change rather than a part. I started asking why the system could not notice its own drift, and nobody I worked with could tell me more than "that's how it came". That question is what I want to spend a degree answering properly. Intelligent systems engineering attracts me because it sits where I already work in a rough, practical way: sensors producing messy signals, controllers making decisions, networks carrying data somewhere useful, and people who have to trust the result. I want the underlying theory, particularly control, signals and embedded software, so that I can design the behaviour of a system rather than just restore it to factory defaults. I am also interested in the integration side, where separate subsystems from different manufacturers have to agree on something. Returning to study at 29 is a deliberate choice rather than an escape from my job. I liked the work, but I could see the ceiling from where I stood, and it was made of things I did not understand yet.

How have your qualifications and studies helped you to prepare?

My Access to HE Diploma in Science and Engineering has been the most demanding thing I have done, largely because I did it while working shifts. I sat down with the timetable in September and worked out that I had roughly two clear evenings and most of Sunday, and I have protected that time since. Mathematics has been the core of it. I had forgotten almost everything from A-level, so I rebuilt from indices and rearranging formulae up to calculus, and I now find differentiation genuinely enjoyable when it describes something changing in time. Working through first-order differential equations and seeing an exponential approach to a steady temperature explained years of watching cold stores pull down after a defrost cycle. The electronics unit covered operational amplifiers, filters and logic, and I chose a research project on closed-loop control, comparing simple on-off control with proportional control and explaining overshoot and hysteresis in terms I could have used with my old colleagues. I have also had to learn how to write again, using references properly and keeping an argument tidy, which my tutor pushed me hard on. Alongside college I have been reading around the subject, including Bishop's Control Engineering and parts of Norvig and Russell on search and probabilistic reasoning, and I use the Horowitz and Hill circuits book as a reference when my breadboard misbehaves.

What else have you done to prepare outside of education, and why are these experiences useful?

Work has given me habits that college did not have to teach me. In the warehouse I was responsible for stock accuracy on a section of racking, which meant tracing discrepancies back through scans and paperwork until something made sense; I am comfortable being methodical when the answer is not obvious. On maintenance I learned to test one thing at a time, to write down what I changed, and to explain a fault to a kitchen manager who needed to know when they could cook again rather than what a thermistor is. I still do occasional weekend shifts, which pays for my studies and keeps me honest about how equipment behaves outside a lab. At home I have built a monitoring setup for my flat using an ESP32, a temperature and humidity sensor and a light sensor, logging to a small database and plotting the results. It began as curiosity about damp in the back bedroom and turned into a long argument with noisy readings; I ended up implementing a simple moving average and then a basic complementary filter, and learning why sensor placement mattered more than either. I also help run a five-a-side team, sorting pitch bookings and chasing subs, which is unglamorous but has taught me to keep a group organised without nagging. I play bass badly and repair my own amplifier, which is how I first learned to solder. I am ready for the workload and looking forward to it.
