Abstract
The human heart has three main parts with oscillating behavior. If the performance of any of these three parts is disturbed, diseases such as bradycardia will occur. To cure the disease, an external electrical signal must be applied to the heart. This external signal can be calculate by a closed loop control system. In this paper, a nonlinear control system has been designed to track the normal heart rate signal in people with bradycardia disease. Due to the nonlinear behavior of the heart and its multivariate dynamics, the controller is designed using the nonlinear MIMO feedback linearization method. Also the unmeasurable and uncertain functions are estimated using an extended state observer. In computer simulation, the performance of the designed control system is investigated.
