Abstract

By using the Virtual Instrument LABVIEW, establish a data collection and handling system which is used to do open-loop system identification on VAV System Terminal. By employing the step-response method, measure the minor loop control plant-air valve characteristics. By using the M-sequence as the input stimulating signal and least square method as the simulation algorithm, carry on system identification on major loop control plant-room. After simulation process, calculated model turns out to be reliable through white-noise test.
