Наслов: | ANALYTICAL CALCULATION OF THE POSITION LOOP GAIN FOR LINEAR MOTOR SERVO DRIVES FOR CNC MACHINE TOOLS | Authors: | Zoran PANDILOV | Keywords: | analytical calculation, CNC machine tools, linear motor, servo drives, position loop gain | Issue Date: | јун-2023 | Publisher: | Editura Politehnica | Journal: | Academic Journal in Manufacturing Engineering | Abstract: | One of the most important factors which influence on the dynamical behavior of the linear motor servo drives for CNC machine tools is position loop gain or Kv factor. From the magnitude of the Kv-factor depends tracking or following error. In multi-axis contouring the following errors along the different axes may cause form deviations of the machined contours. Generally position loop gain Kv should be high for faster system response and higher accuracy, but the maximum gains allowable are limited due to undesirable oscillatory responses at high gains and low damping factor. Usually Kv factor is experimentally tuned on the already assembled machine tool. This paper presents a simple method for analytically calculation of the position loop gain Kv. The influence of nonlinearities was taken with the correction factor. Our investigations have proven that experimentally tuned Kv factor differs from analytically calculated Kv factor less than 10%, which is completely acceptable. | URI: | http://hdl.handle.net/20.500.12188/30665 |
