Control System Design of Syringe Infusion Pump and MATLAB Simulations

Infusion pumps have multiple uses according to their location. According to its use, there is a need to specific control parameters. The objective of this study is to implement and to assembly all the modules of an infusion pump, controlling all the functions. The control was implemented with the computer board based MATLAB and a web page was developed to assist the user to record, retrieve and access information about the operating conditions. Syringe infusion pump mechanism is controled by an endless thread and a dc motor. A FOPID (Fractional order Proportional, Integral, Derivative) and PID controller is developed in position and velocity conrol of dc motor. GUI (General user interface) - MATLAB program is presented so that to help the user and patient. Performance of the control systems of infusion pump is investigated and discussed by MATLAB simulations. Finally when a classical PID and FOPID controller are implemented, the position and velocity responses of the infusion pump mechanism are compared.
