PERBANDINGAN JUMLAH MEMBERSHIP DAN MODEL FUZZY TERHADAP PERUBAHAN LEVEL PADA TANGKI AIR BERBASIS LabVIEW - myRIO

Abstract

Controlling the water level is a very important system in the process industry. In general, variable level control is done by using the control valve included in the control level. In this study, two tanks were used, namely measuring tank and storage tank and there was a manual valve. The water level height of the measuring tank depends on the setpoint value. And it is also necessary to keep the water level in order to stay in line with the setpoint. In this study, the authors will compare 3 responses, namely 3 Memberships with Triangle models, 5 Memberships with Trapezoid models, and 7 Memberships with Gaussian models. The system consists of LabVIEW, NI-myRIO, ultrasonic sensors, drivers, dc pumps, stop faucets. NI my-RIO was the primary control for this study, where NI-myRIO will retrieve data from ultrasonic sensors that are then displayed on LabVIEW. The data shown in LabVIEW is the data for the water level. Drivers are here as an additional circuit controlled by pwm to control the dc pump. Based on the results of the research conducted, it can be known that the number and model membership affects the time for stable water. The response of 7 memberships with Gaussian models has the fastest time to stabilize with a time of 16 seconds
