Double-integrator control (1): motivation (position control, force actuator, cascade control)

[@rezah336]

why not make an example? make a system and control it...

Thanks for the comment! This is part of a case study, with 7 videos planned... But it'll take some time to complete and I have other videos with other topics in publication queue. It's the first one with just a bit of "motivation" towards understanding what might mean in "practice" what we'll do in next videos when devoting a lot of time to theory and simulation with the transfer function 2/s^2. Nevertheless, I'm a theory guy so the forthcoming videos will deal with ode45 simulations, pole placement, Laplace transform manipulations and the like. Actual "motion control" equipment will be for sure better presented in websites and YT channels of commercial companies in the area, I guess. Spoiler: motion control with reducing gears, hydraulics, etc. is better modelled with 1/s (kinematic control) than with 1/s^2 (dynamic control)... Keep tuned !-)
