摘　　要：改进了一个心脏起搏器混沌状态的数学模型,对其基本动力学行为进行了分析,数值模拟和电路仿真证明了该模型的混沌特性.利用线性反馈理论,设计了一个简单的线性反馈控制器,对心脏起搏器混沌模型进行控制研究.结果表明:线性反馈控制器能够很快将模型由混沌状态控制到周期状态,即从病态恢复心脏起搏器正常运动机制,从而使心脏恢复窦性心律.A mathematical chaotic model of pacemaker was improved in this paper. The basic dynamics analysis was given,numerical simulation and circuit simulation were carried out to prove the chaotic characteristics of the model. Using linear feedback theory, a simple linear feedback controller is designed to control the pacemaker chaos model. The numerical simulation and circuit simulation results show that the linear feedback controller can quickly control the model from the chaotic state to the periodic state. That is recovered from the pathological normal pacemakers motility mechanism,so that the heart to restore sinus rhythm.
