基于虚拟仪器的非稳态流管道参数辨识
Pipeline parameter identification of non-stationary flows based on LabVIEW
摘要
Abstract
To realize pipeline supervisory control,a monitoring system is established for signal trans-mission,data acquisition, data recording, real-time signal display and so on by using an embeded measurement and control platform CompactRIO with laboratory virtual instrument engineering workbench( LabVIEW ) which can be configured renew. According to the initial conditions and boundary conditions,the distributions of velocities and pressures for a pipeline model are calculated using the method of characteristics. The parameters are identified using the particle swarm optimization algorithm,and the calculation and measurement results are compared. The results show that the measurement values are approximate to the theoretic values of parameter identification,which shows the effectiveness of the method.关键词
