基于模糊PID + PLC控制的配料包装系统设计

Design of Packing System Based on Fuzzy PID + PLC Control

针对我院种业公司包装系统稳定差、精度低的特点,设计了一种模糊PID与PLC技术相结合的自动配料称重包装控制系统,给出了详细的系统结构、具体的控制方式和实现方法,详细论述系统硬件电路设计和软件设计方法。运行表明,系统包装精度和工作稳定性都得以明显改善,实用价值高,值得推广。

Aiming at our seed company with the characteristics of the poor stability and low precision, this paper proposes a automatic batching packing system based on fuzzy PID + PLC technology, and gives the system structure, control and the concrete implementation method, and also gives an explanation for hardware design and software design of the key part. The trial showed that the precision and working stability of packing system are obviously improved, which has a certain practical value and popularization value.
