Inertia Identification of Servo System Based on Improved Acceleration Deceleration Method

In order to improve inertia identification accuracy of the servo system, this paper proposes an improved acceleration deceleration method which adopts a simplified mathematical model of servo system in rotating coordinate system of servo motor, determines the detection signals which applies for load inertia identification. The experimental results demonstrate that compared with traditional acceleration deceleration method, the improved acceleration deceleration method has significant improvements in the accuracy of inertia identification and thus the study results have a major impact on the improvement of servo system's control performance.
