The Application of Fuzzy Control in Metal Packing Machine Control System

为提高金属打包机的工作效率、性能和使用寿命,提出将模糊控制技术应用到金属打包机控制系统中。分析与设计了模糊控制器,包括输入量和输出量的模糊化、确定语言值的隶属函数、模糊控制规则的建立、模糊推理、解模糊以及量化因子和比例因子的确定;运用了MATLAB/Simulink对控制系统进行仿真,结果表明:该控制系统响应速度快、超调量小、振荡小,满足了金属打包机在复杂工作环境中工作负荷稳定的需求,为金属打包机控制系统的设计提供了依据,解决了在设计过程中控制系统不精确的问题。

In order to improve the working efficiency, performance and service life of the metal packing machine, the fuzzy control technology is applied to the control system of the metal packing machine. The fuzzy controller is analyzed and designed, including the fuzzification of inputs and outputs, the selection of membership functions, the establishment of fuzzy control rules, fuzzy reasoning, ambiguity, resolution, and the determination of quantization factors and scale factors. The system is simulated by MATLAB/Simulink, and the results show that the control system has fast response, small overshoot and small oscillation, which meet the demand of work load stable of metal baler in the complex working environment, provide the basis for the design of control system of metal packaging machine, and solve the inaccurate problem of control system in the design process.
