Autotuning by Aerotech

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 stabilising controller followed by progressively more sophisticated compensation via loop-shaping procedures.

EasyTune was 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 the Automation 3200, Ensemble, and Soloist families of controllers.
