Design and Implementation of an Electric Actuated Valve for Precise Fluid Control

Abstract

Fluid control is one of the essential automation application area in industry. In order to fluidcontrol effectively and precisely, valves which are crucial components, need a controlled rotatingmotion which leads to implement electric motors, electronic controller and gear systemsaltogether. In this study, an electric motor actuated valve system is designed and prototyped. Thedesign phases are including switch mode power supply (SMPS) design, motor controller circuitdesign, mechanical implementation and controller design. The designed valve system ismanufactured and tested using multi-disciplinary fashion. The application problems are solvedby using the proper control techniques and strategies. The precise position control of butterflydisc is also achieved. According to the related industrial standard and application requirements,the experimental results show the effectiveness of the design approach.
