Many existing tuning techniques rely on basic model-fitting or “rules-of-thumb” that ignore machine resonances or nonlinear behavior, but EasyTune directly measures and compensates for those effects. It assumes no prior knowledge of the system properties, and begins with a system identification operation. It continues with the development of a baseline stabilizing controller followed by progressively more sophisticated compensation via loop-shaping procedures. The final controller has the highest bandwidth practical for that particular stage system.
Aerotech: Commercial motion controller
EasyTune from Aerotech is the most advanced autotuning tool available in a commercial motion controller; entirely data-driven, the algorithm largely mimics the process followed by an experienced controls engineer.
