| 目的 为了提高产业中啤酒罐装的质量和效率，精准控制储液罐内液位。方法 利用双容水箱建立实验数学模型，在PID串级控制和DMC控制等2种算法下仿真，并进行参数整定，对比分析仿真结果。应用OPC技术实现King ACT和组态王数据通信来设计监控界面。结果 DMC控制汲取PID的快速性和串级控制响应快的特点，使得整体具有响应快、稳定性好和超调量小的特性。监控界面可以实时形象地反映控制过程。结论 该控制系统控制性能佳，鲁棒性强，且成本较低，可用来提高啤酒罐装机灌装效率。 |
| 英文摘要: |
| The work aims to improve the quality and efficiency of beer canning in the industry, so as to precisely control the liquid level in liquid storage tank. The mathematical model of the experiment was established with the double-holding tank. The simulation was carried out under the two algorithms of PID cascade control and DMC control, and the parameters were tuned. The simulation results were compared and analyzed. OPC technology was applied to achieve the data communication between King ACT and King View, so as to design the monitoring interface. The results showed that, DMC control absorbed such characteristics as PID rapidity and fast response of cascade control, which made the whole system featured by fast response, good stability and small overshoot. The monitoring interface could visually reflect the control process in real time. Characterized by good control performance, strong robustness and low cost, the control system can be used to improve the efficiency of beer canning machine. |
