ADRC applied in chaotic arrhythmic heartbeats control

Control arrhythmic heartbeats has always been an important issue in cardiology. In this work, the capability of active disturbance rejection control (ADRC) to suppress the chaotic arrhythmic heartbeats is studied. The modified Van der Pol model is employed as mathematical model to describe the normal and pathological heart rhythms. The ADRC method is applied in three channels of the chaotic cardiac model. Compared with the commonly used time-delayed feedback control method, the ADRC method manifests better performance, thus worth further investigation and development in the field of chaotic arrhythmic heart beats control.
