About

Sun, 17 May 2026 00:00:00 +0000

I’m Aris Papasavvas, a control and automation engineer with industrial and academic experience across fuel cell systems, test benches, real-time optimization, PLC-based control, and all the messy reality between theory and commissioning.

ArisNotes is where I put what I build and learn : guides, projects, and rougher notes on control, automation, optimization, and embedded systems. The goal is simple: make things practical and reusable for engineers facing similar challenges.

Automation Guide

Sun, 17 May 2026 00:00:00 +0000

On the field, control and automation systems are implemented using very specific tools like PLCs : tools that are usually not taught, or even mentioned, in non-technical-focused universities. However, if you’re pursuing a career in industrial control and automation, hands-on experience with these tools is essential. I had to learn them on my own, and here I’m trying to share the material I wish I’d had to speed up that process. Here I will be talking about tools, programming strategies, and everything that constitutes the bridge between control theory and its application on a field computer.

Cascaded control - Time separation

Sun, 17 May 2026 00:00:00 +0000

This note explains why time-scale separation is key in cascaded control, and how it helps you avoid unexpected oscillations when stacking controllers. It gives an intuitive rule of thumb (and where it comes from) so you can design inner and outer loops that play nicely together—whether you’re tuning simple PIDs or building more advanced control layers.

From Obsidian notes to a local Hugo website

Sun, 17 May 2026 00:00:00 +0000

TLDR : This note walks you through turning your Obsidian notes into a local Hugo website using the Roadster theme, from creating the site folder to configuring the hugo.toml file. It’s a step‑by‑step, copy‑paste‑friendly guide so you can get a basic blog up and running quickly, then start customizing the look and layout to your taste.

Hugo from local to website

Sun, 17 May 2026 00:00:00 +0000

This note walks through a practical way to deploy a Hugo website from your development PC to a live server, using GitHub as the bridge and automation layer. It helps you put in place a clean workflow for building locally, versioning your site, and pushing updates to production with as little manual work as possible.

Optimization Guide

This is the main note for my Optimizations Guide.

quaternions - Application to drones orientation

Sun, 17 May 2026 00:00:00 +0000

This note shows how to use quaternions to track a drone’s 3D orientation in a clean, implementation‑friendly way, starting from gyroscope data and then correcting drift with the accelerometer (and later the magnetometer). It walks through the math and the approximations step by step, so you can turn raw IMU readings into a stable attitude estimate that actually runs on an embedded controller.

quaternions - The tool to deal with 3D orientation & rotations

Sun, 17 May 2026 00:00:00 +0000

TLDR : This note introduces quaternions as the natural 4D extension of complex numbers for handling 3D rotations, starting from the familiar 2D case. It shows how to build rotation quaternions and apply them to vectors, giving you a clean, mathematically sound way to represent orientations and rotations in 3D space without relying on Euler angles.

The Lagrangian

Sun, 17 May 2026 00:00:00 +0000

This note gives a geometric, engineer-friendly view of nonlinear optimization and shows how the Lagrangian turns “constraints plus objective” into a single analytical object. Along the way, it builds up the ideas of Lagrange multipliers and KKT conditions step by step, so you can see them as sensitivity measures and practical optimality checks rather than abstract math.

Bode Diagram

Sun, 03 May 2026 18:54:00 +0000

This note gives you an intuitive, practical way to understand what Bode diagrams really tell you: how your system reacts to different frequencies in terms of gain and phase. It also shows where this comes from and how to quickly approximate Bode plots, so you can analyze systems, tune controllers, or design filters without getting lost in heavy math.
