IDENTIFIKASI DAN DESAIN CONTROLLER PADA TRAINER FEEDBACK PRESSURE PROCESS RIG 38 – 714

Abstract

Pressure Process Control of Trainer studying to control air flow in order that stable. input system is Pressure and have current 4 – 20 mA. That current will thought I/P converter until produce pressure to move pneumatic valve. Effect Change of Position valve make controlling air flow.it is detected by pressure sensor and produce signal output voltage. System Pressure Process Control is nonlinear so must design PI Controler to produce stable pressure for a moment given disturbance. Result this paper show PI controller can be stable pressure air flow with time steady state 12 secon.
