Aerotech: Commercial motion controller

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.
