Adaptive control application on syringe pump pressure control systems in oil and gas industries

Abstract

Syringe pumps have found various applications in the oil, gas, medical, and pharmaceutical industries. A high-precision pressure control approach is required in order to have accurate results in laboratories experiments. In conventional control systems, users need to regulate system controllers because of the various operating points. Adaptive control consists of several techniques which enable engineers to adjust control system parameters in real time automatically. In this paper, an appropriate adaptive controller is designed and implemented to provide meticulous operation of the syringe pump's motor in a wide range of operating points. The drive system of the permanent magnet synchronous motor is designed to control the fluid pressure through the syringe and needle. The experimental results demonstrate the accuracy and effectiveness of the proposed control strategy in comparison to the conventional controllers.
