Abstract
The total artificial heart(TAH)is an electromechanical device to be
integrated with mammal’s blood flow dynamics to reinstate the functionality of biologically defected heart.This thesis presents a Halbach array linear synchronous motor(HALSM)which is used as a TAH.The TAH requires special design requirements for developing sufficient amount of force and small losses.Analytical formulas for the HALSM developed force are 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). Depending on FEM,the full design details of the HALSM TAH are determined.The dynamic model of the blood circulation driven by HALSM is utilized as a main step before control system design.The optimal control of the TAH that utilizes HALSM is studied to investigate its performance to drive the human blood circulation.The optimal control system aims at enabling the TAH to follow certain pattern of blood flow.A PID controller is designed to control the TAH system. The genetic algorithm(GA)is used to obtain the optimized controller parameters.Simulation study is carried out for the TAH under optimized control as integrated element in the blood cycle
of an adult human.The obtained results present valuable guide for the design of TAH implementing Halbach linear motor and its control system.
