Can you elaborate on cascading PID .
at what frequency should i change my motor speed .
Is 100 hz fine for PID ?"
Dean Lamborn replied to William Bishop's discussion Heavy Lift Quad"As long as you are using a standard ESC it doesn't matter what the size of the vehicle might be.
The reaction to inputs is a function of the PID tuning. Fast response is a function of how much power you have in reserve. If you are committing…"

Known as the Terrestrial Artificial Lunar and Reduced Gravity Simulator, or Talaris, the three-foot-wide vehicle is a smaller version of a hopper that would be used in space. It is designed to go about 20 meters per hop; space-based hoppers might cover tens of kilometers--or possibly more--in a single bound. The team that built…
