I'm trying to understand something very basic about Control Theory. Let's say I have the following loop:
If we'll relate this loop to a cart with a motor going in its single axis from X = 0 to X = 50, the controlled variable will be the engine speed (v), while the monitored variable will be the cart location (x).
In this case:
The measured output should be the cart location, right? But the system output should be the engine speed, shouldn't it? If so, how does this work in the equations? (units-wise)
What will be the Reference, System Input, System Output?
