Real-time implementation of feed rate active force control of a syringe fluid dispenser
Siti Khadijah Badar Sharif1, Musa Mailah2.
For precise application, it is imperative to provide accurate and stable performance. The
feed flow rate of a syringe fluid dispensing system is regulated through a ProportionalIntegral-Derivative
(PID) and Active Force Control (AFC) control scheme that was
actuated using a DC servo motor considering a real-time implementation. The focus of this
study is to control the speed of a DC motor by implementing an AFC strategy in rejecting
the disturbance in the system. The AFC is implemented by cascading its control loop with
the outer PID controller loop to form a two degree-of-freedom (DOF) controller. The
performance of the proposed PID with AFC control scheme was investigated considering
both the theoretical simulation and experimental works. The simulation was performed in
MATLAB/Simulink computing platform while the real-time experimentation was done by
utilising the Arduino MEGA 2560 microcontroller with MATLAB/Simulink driver for the data
acquisition, interface and control implementation. The results implies the robustness of the
AFC-based system in controlling the feed flow rate of the fluid in the dispenser. The best
performance is obtained for 100% AFC with the disturbance due to vibration almost
completely compensated via the proposed scheme in comparison to the PID counterpart.
