Abstract :
In this paper, controller for a human brachial artery system prototype is formulated with respect to a static model. Operational procedure of the designed prototype has been highlighted. Because of linearity of the designed system, major components (pump and shaker) are considered autonomously during preliminary analysis. Ziegler - Nichols tuning methods and pole placement scheme have been utilized to calculate the controller parameter values. At the concluding stage, the computed values for pump and shaker are combined to denote the overall response of the system. Simulation results have been presented to verify the correctness of the utilized techniques. It has been concluded from obtained results that the determined controller parameter values for both pump and shaker are more than satisfactory for all three typical test inputs.
