Pittsburgh, PA - Aerotech's EasyTune advanced autotuning tool for the company's motion controllers is entirely data-driven and largely mimics the process followed by an experienced controls engineer. The tool directly measures and compensates for machine resonances or nonlinear behavior effects, assuming no prior knowledge of system properties and beginning 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.

The tool 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. It is a standard feature of the company’s A3200, Ensemble, and Soloist motion controllers.
