October 1, 2015 - Aerotech announces EasyTune autotuning tool for motion controls.

Entirely data-driven, 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, 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. EasyTune was extensively tested and refined on hundreds of different motion systems, including on systems with different bearing styles, drive technologies, and mechanical configurations. It requires no input from the user, completes in a few minutes, and provides measured verification of the servo performance when complete. EasyTune is a standard feature of Aerotech’s A3200, Ensemble, and Soloist motion controls.
