【摘要】 自动配料系统的恒流量控制采用PID调节,流量计量控制是计量偏差与变频调速的结合。依据系统工艺流程介绍了配料系统的流量控制方式和系统控制过程,详细讲述了PLC的选型及PLC配料系统变频控制中的硬件设置、参数设定和软件设计过程。更多还原

【Abstract】 The auto-dispensation system permanent flow control uses the PID adjustment, the current capacity measurement control is measures the deviation and the frequency conversion velocity modulation union. Introduces the flow-control mode and control process of the system based on the systems manufacturing process of the allocation. This essay also illustrates the hardware setting and soft-ware designing of PLC selection, frequency conversion control of allocation system in detail.更多还原
