| 摘要: |
| 针对茶叶杀青原系统中PLC对DTA温控器的PID控制参数设定问题,将开关量控制的DTA温控器替换为三相交流调压模块,优化设计出自适应控制系统。自适应控制系统中的PLC的温度控制信号经三相交流调压,输出可变电压对杀青机加热,并采集杀青机的温度信号反馈回PLC,构成闭环控制回路,实现连续地对滚筒杀青机加温,达到最优化的温度控制效果,提高茶叶的杀青质量。 |

| Abstract: |
| The problem in the original tea green removing system is to set PID control parameters in DTA thermostat.In order to solve this problem the on-off control thermostat with three-phase AC voltage regulator module was replaced and an optimizing adaptive control system was designed.The temperature control signal,which from PLC in adaptive control system,was first sent to three-phase AC voltage regulator module to generate variable output voltage for heating in the green removing machine.The temperature signal of the machine returned to PLC.A closed-loop control circuit was setup,which can continuous heat in the green removing roll machine,achieve the optimum temperature control effect and improved the quality of green tea removing. |
