Estimating the maneuver quality of an automatic motion inverter for end-of-line tuning in agricultural tractors

摘要

End-of line tuning is a crucial step for any mass-produced system endowed with automatic controllers. As a matter of fact, due to components tolerances and spreads in the production line, the controller tuning performed on a prototype system in never optimal on the final product. In many industrial applications, though, the end-of-line tuning is performed by human testers, and this does not always guarantee an objective assessment of the controlled system quality. This paper proposes a way to estimate the maneuver quality from measured data for an automatic motion-inverter in agricultural tractors. The final goal is to automatically classify the performed maneuver and label it with a quality attribute matching that assigned by the driver. This is the initial step necessary to implement an automatic tuning system which can change the controller parameters until a predefined quality on the motion inversion is achieved.
