Parameter Identification of Servo Control System Based on Unbiased Least Square Method

Wu Lulu;Han Jiang;Tian Xiaoqing;Xia Lian;Hefei University of Technology;  
Aiming at accurate parameter identification of a servo control system and the demands of high performance motion control algorithm,a typical servo control system model was analyzed and the unbiased least square method was designed based on Coulomb friction and viscous friction model.Implementation methods of it were studied on the hardware of industrial PC and motion control card.Motor angular speed data was collected in real time.The inertia,viscous friction and Coulomb torque of system were estimated using the least square method.The validity and the correctness of parameter identification were verified through reconstructing the angular speed,comparing the actual measurement with theoretical calculation angular speed.Theoretical observation and experimental results show that the parameters of the servo system can be accurately identified in this kind of CNC system platform with the unbiased least square method.
