| Abstract: | The chaos phenomenon of coronary artery systems can lead to serious health problems. Taking nonlinear coronary artery systems as the research object, a dynamics model of uncertainty in coronary artery systems was established, and the differential-integral terminal sliding mode control (DI-SMC) was investigated for the uncertain coronary artery system. The disturbance observer was designed for the uncertainty of the model. Stability of the designed control system was proven according to the Lyapunov theory. The feasibility and effectiveness of the proposed chaos suppression method was verified using simulation results. |
