Realization of Proportional-Integral Stirring Controller for Mixing Operation in Microbioreactor (original) (raw)

2013

Abstract

In this paper, we presented the establishment of a cheap and simple stirring platform for microbioreactor operation. The stirring platform was designed to provide necessary mixing via magnetic stirrer bar for a microbioreactor setup. The microbioreactor (volume ~ 300 L) used in this investigation was fabricated out of the poly(methylmethacrylate) (PMMA) polymer material via micromachining. Programs for the control routines were written in LabVIEW TM software (National Instruments, Austin, TX, USA), and were implemented by interfacing the LabVIEW TM programs with a data acquisition (DAQ) card (NI USB-6343, National Instruments, Austin, TX, USA) for data logging and sending signals to actuators. The paper first described the details of the mechanical design of the stirring platform and the microbioreactor prototype used in the work. Secondly, experimental results obtained to assess the mixing quality of the reactor and to characterize the performance of the controller in terms of con...
