Advanced autotuning tool available in commercial motion controller

AEROTECH EasyTune advanced autotuning tool in a commercial motion controller is entirely data-driven, as the algorithm largely mimics the process followed by an experienced controls engineer. Many existing tuning techniques rely on basic model-fitting or ‘rules-of-thumb’ that ignore machine resonances or nonlinear behavior, while device directly measures and compensates for those effects. Product 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. http://www.aerotech.com
