Do people actually do systems design with control theory? I know the authoritative question to possibility - yes, my company does it. But I'm wondering about say, an industry standard formalism to it, such as like how DDIA is household
Somewhat, but for distributed systems I’ve found game theory to be more useful. Which does end up looking like high-order control theory in many cases.
It’d be nice but in my experience I’ve seldom seen that much thought put into it, even with actual literal control systems. Unless you’re doing something interesting in robotics or aerospace, most stuff gets solved with logic sequences and maybe some PIDs.
