Sebuah Instrumen Virtual Penganalisis Sinyal Dinamik Sederhana untuk Memantau dan Mengontrol Temperatur Aliran Udara
Abstract: This work aims to
present a Dynamic Signal Analyzer Virtual Instrument (DSA-VI) for monitoring
and control the airflow temperature in a prototype of air duct. Here, the
DSA-VI has developed by using LabVIEW software and Arduino UNO. To investigate
the performance of DSA-VI, an experiment has performed to monitoring andcontrol
airflow at settling temperature, 40oC, 50oC, and 60oC, respectively by using
the DSA-VI. By assumingthat an airflow temperature control system as the first
order system, the time constant () should be
inspected asone of the system characteristics. The testing at the
settling and surrounding temperatures (Tsp and T0) are 40oCand 28.81oC
respectively, obtained value of is 7.49 s; at Tsp
and T0 are 50oC and 29.88oC respectively, obtained value of is 11.35 s; and at Tsp and T0 are 60oC and 28.81oC respectively,
obtained value of is 19.54 s. By using DSA-VI, the value of at the transient response can be evaluated. At the steady state
response, the airflow temperature has controlled well with the steady
state error less than ± 2.5 %.
