摘要
This paper presents an adaptive observer for friction identification and compensation in a linear servomotor. The objective is to compensate the dead-zone phenomena caused by static and Coulomb friction and improve the tracking accuracy of the positioning system. Friction is treated as a time varying disturbance to the system and the adaptive control system is designed to compensate for the nonlinear friction without establishing any friction model. Experimental results are provided to confirm the effectiveness of the adaptive compensation scheme.
