| Abstract | ||
| The total artificial heart (TAH) is a mechanical device to be integrated with mammal‟s blood flow dynamics to reinstate the functionality of biologically defected heart. In this paper, a Halbach array linear synchronous motor (HALSM) is used as a TAH. In this paper, the optimal control of the TAH that utilizes HALSM is studied to investigate its performance driving blood circulation. The optimal control system is relied on enabling the TAH of following certain pattern of blood flow. Analytical formulas for the HALSM developed force is presented depending on space harmonic analysis for the solution of the multilayer boundary field problem. Parameters of the formulas are obtained by means of magnetic field analysis using finite element method (FEM). The dynamic model of the blood circulation driven by HALSM is developed as a main step before control system design. PID controller is designed to control the TAH system. The genetic algorithm (GA) is used to obtain the optimized controller parameter .Simulated study is carried out for the TAH optimal control as integrated element in the blood cycle of an adult human. The obtained results, presents valuable guide for the design of TAH control system implementing Halbach linear motors. | ||
