A Control System Design for Nanoparticle Manufacturing by Using Im-Pinging-Jet Micromixers

Article Preview

Abstract:

In this paper, a novel control system is introduced for a micro process system for the manufacturing of nanoparticles. An impinging-jet micromixer is used as the microreactor for mixing two fluid phases. In order to increase the scalability of the manufacturing system, a high speed image acquisition and processing subsystem is utilized to provide real-time visual feedback. Jet slope and shape are calculated automatically to evaluate the outcome of the mixing. A control algorithm consisting of a feedforward and feedback components is then implemented to control the pump’s flowrate to deliver guaranteed performance even with the presence of external disturbance and system uncertainty. Experimental results show the feasibility of the proposed solution.
