N2 - In order to solve the problem of dynamic non-synchronous widely existing in dual drive machine tools, the non-synchronous errors were measured and a compensation controller was designed. First, a kind of S accelerate/decelerate curve was deduced, the dynamic non-synchronous errors were detected using linear scale. Second, PID compensation controller was designed to compensate the non-synchronous errors and the parameters of PID controller were obtained by means of Z-N method. Finally, some experiments were carried out on DK-1200 gantry-type machine tools with travelling bridge. The results show that PID controller has a satisfactory performance.
