Automatic production line includes machinery, electric, control, communication and other multi-disciplinary technologies and knowledge. It is an ideal training platform for students majored in mechatronics and electric automation. In the designing of platform, however, the difficulty lies in the precise delivery and position control of linear guide rail system. To address this problem, this paper aims at designing an AC servo-control system based on PLC, AC servo driver, servo motor and human-machine interface (HMI) and elaborates the principle of servo-control system, circuit design and software design. The system will achieve reliable delivery and precise positioning with position error less than 1 mm, which, with great application value, will meet the actual demand from industrial production.

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.
