Abstract

Abstract:

Based on the principles of PLC and stepper motor, an automatic control system was designed to realize the flexible displacement control of the movable limiter on HL-3 tokamak. A two-phase hybrid stepper motor was selected, and the S7-1200 PLC was used as the stepper motor controller. The open-loop speed control and position control of the actuator driving stepper motor of movable limiter were achieved through motional axis configuration and the application of PLC-open motion function blocks. At the same time, human-machine interface interaction was implemented, which achieved real-time display of the HL-3 movable limiter displacement, parameter setting, automatic feedback control, and threshold alarm functions. The system has been successfully deployed in the operation of the discharge experiment of HL-3 tokamak. The results since its operation have shown that the designed control system can meet the control requirements and reach the desired objectives.

摘要： 为了实现HL-3 装置活动孔栏位移的自动化控制，基于PLC 和步进电机的应用原理，设计了活动孔栏位移自动控制系统。选用两相混合式步进电机，采用S7-1200PLC 作为步进电机控制器。通过运动轴组态，并运用PLC-open 运动功能块实现了对活动孔栏驱动步进电机的开环速度控制和位置控制。同时完成了人机界面交互，实现了对HL-3 装置活动孔栏位移实时显示、参数设置、自动反馈控制和阈值报警等功能。该系统已成功投入到HL-3 装置放电实验运行中。自此系统投入运行以来的结果表明，所设计的控制系统能够满足控制要求，完成了预期目标。
