After reading the excellent writeup on partitioning of the European Power Grid, and more recently about automotive CAN networks, I'd like to learn about writing software for safety systems.
Where is a good source of the basics? Thank you!
Control theory is the best place to start (analog) before digital control theory, but it is a lot of math.
Digital controls is a way of building discrete (sampled rather than continuous) models and systems. Almost all control systems these days are digital—-but even modern equipment like aircraft still have some analog control systems.
To write software for safety systems such as power grid control, you should understand the fundamentals and applications of digital control theory so that your requirements, design and software will be effective.
