Abstract:
The dual-driving feed system is widely used in highspeed/high-precision CNC machine tools due to its high rigidity. However, when the column moves along the beam, the load parameters of the dual-driving two axes will change, which results in non-synchronous error and affects the machining accuracy. For this problem, an adaptive synchronization tracking control (ASTC) strategy of dual-driving feed system for gantry-type machine tool is proposed. In this control frame, active disturbance rejection controller (ADRC) evaluates and compensates the influence of the internal and external disturbances, realizing the decoupling control of the dual-driving feed system. Besides, the equivalent load masses of the dual-driving two axes can be obtained according to the position of the column on the beam, and the ASTC automatically tunes the controller gains of each axis according to the corresponding load mass. The simulation results show that the proposed ASTC has better tracking performance and dual-driving synchronization performance. © 2017 IEEE.
