Advanced Control and Systems Engineering with Extended Research MSc postgraduate personal statement example

Personal statement example

The tenor bell at the church where I ring weighs a little under a tonne. Ringing it well means holding it just past its balance point, mouth upward, and letting it go at exactly the right moment. Pull too hard and it overshoots; too gently and it drops back early. I learned to ring as a teenager, long before I knew the word 'feedback', but when I first met the inverted pendulum in a second-year control lecture I recognised the problem immediately. Keeping something near an unstable equilibrium with small, well-timed corrections is what has held my interest in control ever since, and it is why I want to study it in depth at postgraduate level.

My BEng in Mechatronic Engineering gave me a broad base in dynamics, electronics, signals and programming. The modules I enjoyed most were classical control and an introduction to state-space methods. Working through the derivation of a state observer and then seeing it estimate a velocity I had not measured made linear algebra feel useful rather than abstract.

For my final-year project I built and controlled a small heated seed propagator: a plastic tray with a resistive heating mat, two temperature sensors and a microcontroller switching the mat through a MOSFET. Instead of tuning a controller by trial and error, I wanted to model the plant first. I logged step responses and fitted a first-order-plus-dead-time model. It turned out to be poor whenever the lid was opened, so I moved to a two-state model separating the mat from the air. I then designed a PI controller with anti-windup, because the heater saturated at full power during warm-up and the integral term had been causing a long overshoot. The final controller held the air temperature within about half a degree of the setpoint in steady conditions. It was slower to recover from disturbances than I had hoped. My report discussed why, and suggested feedforward from a room temperature sensor as the next step. The project taught me how much of control engineering happens before the controller exists: choosing what to measure, deciding what to model and judging when a model is good enough.

Since graduating I have worked early shifts in a supermarket bakery, a job I first took part-time during my degree. The work is mostly loading ovens, following bake schedules and cleaning, but it has made me notice systems. The proving cabinet has a humidity setting that staff adjust by feel, and on busy mornings, when the door opens constantly, the dough proves unevenly. I am not in a position to change the equipment. Still, watching a real process behave differently from its specification has been useful, and the job has made me reliable, quick and comfortable working to fixed times alongside people with very different priorities.

Outside work I ring with my local band twice a week and help teach new learners to handle a bell safely, which takes patience and clear, simple instructions. I also sort donations at a food bank on Saturday afternoons. That has nothing to do with engineering, except that a well-organised shelf saves everyone time.

I am applying for an advanced master's with an extended research component because my undergraduate project left me wanting to go further. I want to properly understand optimal and robust control, model predictive control and estimation, and to spend enough time on a research problem to do more than a first attempt. I am particularly interested in control of systems where models are uncertain or change over time, such as thermal processes in buildings. Longer term, I would like to work in industrial control or continue into research. I can offer a solid grounding in the fundamentals, practical experience of taking a system from measurement to working controller, and a steady, persistent approach to problems that do not behave as expected.
