What is the expected differential error in the RMP220?

Post by ChrisC »

What is the expected differential error between requested movement and actual movement of the RMP? What affects do external criteria, such as surface, payload, uphill/downhill position etc. have on the error state?

The steady state error in the yaw rate controller is very low (<1%) for the default payload range, on a high traction and level surface, with the tires inflated to the spec in the manual.

Surface traction, tire pressure, high payloads, and slopes will all effect the steady state error to some degree but given the number of variations we have no empirical data.
