Back in signals and systems class we actually formalized the difference in controlability between continuous time with X ms delay vs discreet time at Y Hz. The specifics escape me, but the summary was obvious: always prefer continuous, minimize X.
- blt 3y agoWhat about x = 1000 ms and y = 1000 hz?
- explaininjs 3y agoContinuous is still better because you can react to changing state at every moment rather than being stuck with a response for a whole second. I believe the threshold ratio is somewhere around e. You might find MIT’s 6.302 lectures enlightening.
- explaininjs 3y agoI misread, I’d expect 1000 hz to respond better than 1s delay yes.
- user_7832 3y agoCould you expand a little on this? It sounds interesting. Thanks!
- explaininjs 3y agoI’m too far removed to be able to expand with much authority at the moment unfortunately. That said the notes and readings on this site should be helpful: https://introcontrol.mit.edu/fall21/extras https://introcontrol.mit.edu/fall21/extras
- user_7832 3y agoThank you!

- phkahler 3y agoYou have inertial sensors in your inner ear. There is no fixing a signal that's not even there ;-)
