| 目的 包装机热封切刀温度控制系统存在非线性、大滞后性等特点，传统PID控制的效果也越来越无法满足工艺生产的要求，为了提高包装机热封切刀温度控制的速度和精度，进而提高封口的质量，以提高产品包装效率和品质。方法 在传统的PID控制的基础上，通过结合模糊控制和内模控制理论的先进控制算法，提出模糊内模-PID控制算法的包装机热封切刀温度控制系统。内模控制能够使PID控制器参数进行简化，同时模糊控制的引入能够实现控制器参数的在线调整，将该新型控制算法应用到包装机热封切刀温度控制系统中，并与传统控制进行对比。结果 通过Matlab仿真软件搭建模内模-PID控制的包装机热封切刀温度控制系统仿真平台，仿真结果表明，系统响应速度、精度、超调量、抗扰动能力等比传统控制系统性能更加优良。结论 通过仿真验证了模糊内模-PID控制在热封切刀温度控制系统上的有效性和可行性，能够在温度控制系统中表现出优良的性能指标。 |

| In view of the non-linearity and large lag of the temperature control system for the thermal sealing cutter of the packaging machine, the effect of traditional PID control is increasingly unable to meet the requirements of process production. The paper aims to improve the temperature control speed and accuracy of the thermal sealing cutter for the packaging machine to increase the sealing quality as well as the packaging efficiency and the quality of products. Based on traditional PID control, a temperature control system of hot-sealing cutter of packaging machine based on fuzzy internal model -PID control algorithm was proposed by combining the advanced control algorithm of fuzzy control and internal model control theory. The internal model control can simplify parameters of the PID controller, and the introduction of fuzzy control can realize online adjustment of controller parameters. The new control algorithm was applied to the temperature control system for the heat sealing cutter of the packaging machine and compared with the traditional control. The simulation platform of temperature control system for hot-seal cutter of packaging machine controlled by internal model-PID was built with the Matlab simulation software. Compared with the traditional temperature control system, the simulation system had better performance in response speed, precision, overshoot, anti-disturbance ability, etc. The validity and feasibility of the fuzzy internal model-PID control in the temperature control system of the heat-sealing cutter are verified by simulation. It can show a strong performance index in the temperature control system. |
