Motion Cueing

Motion Cueing if used to let the test subject feel the accelerations. A detailed explanation is beyond the scope of this page.

Response to a short braking and accelerating input

The dynamics and with this requirements for motion cueing for a driving and flying are different and hence we use two different cueing algorithms. For us, the following are the key requirements on our motion cuing algorithms:

  • Motion cues have to happen before visual cues.
  • Eliminate false cues (e.g. the cues associated with the high pass filters and brake release).
  • Be save! (Even if things start to fail, the platform moves safe and controlled).
  • Have a feedback path using accelerometers and gyros to measure the accelerations.
We implemented a variation of the classic motion cueing algorithm adding nonlinear gains and switching to eliminate/reduce false cues. We also have intensive checks, (position and slew limiters).
