Most Advanced Autotuning Tool Available
in a Commercial Motion Controller
EasyTune™ 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. 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.
