In order to further improve the accuracy of the trajectory control and reduce the contour error, a novel method is proposed. This method uses a slight arc segment to approximate the trace curve between discrete points based on the acceleration information. The acceleration information of every discrete point will be provided to the servo control system of each axis to execute the acceleration feed forward control, thus realize the arc connection between the interpolation points. Finally, the simulation experiment results verify the effectiveness of the proposed algorithm.

This paper introduces the structure and working principle of AC servo control system based on programmable multi-axis controller (PMAC). The configurations and parameter tuning method for PMAC PID filters are discussed. It has been shown that, by combining feed-forward control and feed-back control together, the robustness and stability of the servo control system can be improved and the servo tracking error can be minimized if the controller parameters are tuned properly.

In order to improve the performance of the servo control system driven by a permanent magnet synchronous motor (PMSM) under novel direct torque control (NDTC), which, utilizing composite active vectors, fixed sector division criterion, is proposed in this paper. The precondition of the accurate compensations of torque and flux errors is that the sector where the stator flux linkage is located can be determined accurately. Consequently, the adaptive sector division criterion is adopted in NDTC. However, the computation burden is inevitably increased with the using of the adaptive part. On the other hand, the main errors can be compensated through SV-DTC (DTC-utilizing single active vector), while another active vector applied in NDTC can only supply the auxiliary error compensation. The relationships of the two active vectors’ characteristics in NDTC are analyzed in this paper based on the active factor. Furthermore, the fixed sector division criterion is proposed for NDTC (FS-NDTC), which can classify the complexity of the control system. Additionally, the switching table for the selections of the two active vectors is designed. The effectiveness of the proposed FS-NDTC is verified through the experimental results on a 100-W PMSM drive system.

In order to realize the extensive application of technologies of MEVVAII and FAD, the composite equipment has been developed for surface modification and coating films. In this paper, for the first time, the servo control system based on ACR9000 has been used to control workpiece-stage of the composite equipment. Eight target disks are installed on workpiece-stage. Each of target disks can be mounted about 1300 PCB micro tools. So, the equipment can satisfy the requirement for mass production. Experimental results show that the coating unevenness is less than ±14%, better than those of traditional equipments which is less than ±29%. The main purpose of the paper is to introduce the design of workpiece-stage and its three motion modes of rotary positioning, uniform rotation and variable speed rotation, and coating effects corresponding to three motion modes have been verified by experiments.
