I don't know how it's done for planes, but I've heard that many automotive ECUs are programmed graphically, as a block diagram. The engineers basically pretend it's an insanely complicated analog system with amplifiers, filters, switches, and what have you. Then the whole thing gets compiled into a real time binary that simulates the system one timestep at a time.
- mrmlz 5y agoThat is correct for a lot of aircraft systems as well, especially in the design/requirements phase the actual implementation might vary of course. I've personally used Simulink a lot for control systems. I.e. hydraulics, fuel transfers, ECS etc.
- garaetjjte 5y agoYeah, when trying to diagnose issue with my car I found ECU documentation that contained suspiciously complicated block diagrams (with all parameters labeled with abbreviated German), which I'm not sure if they are just documentation or program source itself: https://i.imgur.com/BcW1ho6.png https://i.imgur.com/BcW1ho6.png
