Abstract

The intention of this paper is to design and implement the closed loop control of air flow rate in the air blower system. Desired value of flow rate is provide from the SCADA (Supervisory Control and Data Acquisition) and actual value of flow rate is measured through the flow sensor. Based on the difference between actual and desired value of flow rate, PLC (Programmable Logic Controller) increases or decreases the speed of three phase induction motor through VVVFD (Variable Voltage Variable Frequency Drive) to maintain the flow rate. Obtained results clearly indicate that desired value of flow rate is achieved nicely even under the influence of external disturbance.

Keywords: Programmable Logic Controller (PLC), SCADA, VVVFD, Proportional Integral and Derivative controller (PID)
