Linear feedback control of cardiac pacemaker chaotic model. (Chinese. English summary) Zbl 1449.93061

Summary: 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. This makes the cardiac pacemaker recovered from pathology to the normal motion mechanism, so that the heart can restore sinus rhythm.
