Abstract

Artificial is usually used by heart failure patients with left ventricular failure. Than those where the disease is left ventricular failure, the most common heart disease in recent years is the other auxiliary equipment for the human heart than considered and used. In this paper, for the first time, the uncertainty of the parameters of the system is considered and the range of stabilized parameter uncertainty which return control feedback to the stabilization of the system is calculated. The sensitivity of optimization algorithms to the uncertainties of system parameters are compared and evaluated. The cost function used was based on the model and control method of sampling the pump and the combined statements of speed fluctuation and output functions of the initial cost is presented. In simulation, the effect of controlling these two methods and Akfa sensitivity to parameter changes is compared.
