摘要
基于LabVIEW开发了A3000的实验平台,以进行虚拟仿真控制和实时通信控制实验教学。建立了A3000水箱系统的机理模型,完成了调节阀、变频泵和水箱特性等重要参数的测量和辨识,建成流量调节阀单回路控制、双容串级控制、下水箱前馈反馈控制、比值控制和扩展范围的分程控制等5个控制仿真实验平台。平台采用模块化设计,通过OPCserver与实际A3000装置进行通信,实现了实时控制。
Based on LabVIEW,a process control experiment platform for A3000 is developed,which can realize virtual simulation control and real-time communication control.The mechanism model of A3000 water tank system is established,and the measurement and identification of important parameters such as regulating valve,frequency conversion pump and tank characteristics are completed.Five control simulation platforms are built,which includes single loop control of flow regulating valve,double capacitor cascade control,feed forward and feedback control of sewer tank,ratio control and split-range control of extended range.The platform adopts modular design,communicates with the actual A3000 device through OPC server, and achieves real-time control.
