Implementing a Framework for Closed-Loop Control Algorithms in Modern C++

I wrote up this article exploring how modern C++ features can be used to create abstractions appropriate for embedded and high-performance applications. The framework utilizes features such as:

* template concepts
* NTTP lambdas
* monadic types such as std::expected

In the article, I start with a basic "vanilla" C-style bang-bang control algorithm, and work up to a safer, more performant framework. The flexibility and safety of the interface is demonstrated via examples and even a few fully simulated control laws. The final code is also distributed as a freely available single-header library. There's a few recommended exercises in the article to test your knowledge and get more comfortable with the presented ideas!
