摘　　要：冠状动脉系统的混沌现象会导致严重的健康问题。以非线性冠状动脉系统为研究对象,建立了不确定性冠状动脉系统动力学模型,提出了不确定性冠状动脉系统的微分积分终端滑模混沌抑制方法,针对该模型的不确定性设计了扰动观测器,根据Lyapunov理论证明了所设计控制系统的稳定性,通过仿真实验验证了所提出的混沌抑制方法的有效性和可行性。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 estab-lished,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 suppres-sion method was verified using simulation results.
