MATLAB Real-time Data Acquisition for Laboratory Froth Flotation Automation

In this paper analog input/output signals are used to control laboratory froth flotation machine using industrial panel PC. Dataacquisition is provided by two Advantech PCI cards, while flotation control is based on connection of adjustable frequency drivefurther connected to AC motor for agitation control, mass flow controller for air flow control, pH and temperature transmitters withaccording probes for pH and temperature logging respectively. Process control is provided by graphical user interface programmedin MATLAB.This practical engineering design allows researchers to set parameter values prior to flotation test as well as log and savemeasured values for further processing.
