A Human Brachial Artery System Prototype Controller Calibration (Static Model)

In this paper, controller for a human brachial artery system prototype has been devised with respect to a static model. Operational procedure of the designed prototype has been pointed out. A linear model has been taken in the consideration. Major structural components (pump and shaker) have been treated autonomously during preliminary analysis. Ziegler - Nichols tuning methods and pole placement technique have been utilized to determine the suitable controller parameters. At the concluding stage of analysis, the computed parameter values for both pump and shaker are combined to denote the overall response of the complete system. System has been tested with three typical test inputs: step, ramp and sine functions. 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 typical test inputs.
