N2 - Aiming at the influence of nonlinear friction on the positioning precision of A-axis, two different integral sliding mode controllers were proposed according to different dynamic characteristics of the static and dynamic friction models. When the system was in a different friction stage, the corresponding friction compensation controller would be activated; when the two friction states were constantly switched, the corresponding controller would be switched as well. Experimental results showed that this method could effectively improve the positioning and tracking precision of the A-axis, ensure the blade machining precision and surface consistent, and significantly reduce the surface roughness.
