Abstract :
Cross-coupled control (CCC) is an efficient method for decreasing contouring error, which has been used widely in multi-axes motion systems. The contour error transfer function (CETF), constituted by the response of contouring error between with and without the multi-axis CCC, was introduced to simplify the MIMO system to SISO system. In this paper, the CCC algorithm was introduced to the three-axis stable tracking system, and a biaxial CCC controller was built. Analyses and experiments results suggest that the CCC controller raised target tracking accuracy compared with traditional P controller. In which, the pitch direction tracking error decreased 35%, and the yaw direction error decreased 31%.
