Automatic control systems for the artificial heart (AH) and ventricular assist device were developed using selected criteria of effectiveness, a mathematical model of regulation, and noninvasive measures of the hemodynamic parameters. The Sinus IS2 system was developed for control of the AH; its main component is a high-speed servomechanism that provides for the generation of pneumatic pulses. The servomechanism is controlled by automatic regulation with pressure feedback. Mean aortic pressure was used as the primary regulated hemodynamic parameter. The systems were tested using both a physical model and a physiologic experiment. Contractile insufficiency of the left ventricle was simulated in testing the control system for circulatory assistance. The studies demonstrate that automatic control systems function effectively by providing normal blood circulation in both the resting state and in certain transient processes occurring in a real, dynamic circulatory system.
利用选定的有效性标准、调节数学模型和血流动力学参数的非侵入性测量方法，开发了人工心脏（AH）和心室辅助装置的自动控制系统。Sinus IS2系统是为控制人工心脏而开发的；其主要部件是一个高速伺服机构，用于产生气动脉冲。该伺服机构由带压力反馈的自动调节控制。平均主动脉压被用作主要的调节血流动力学参数。这些系统通过物理模型和生理实验进行了测试。在测试循环辅助控制系统时，模拟了左心室收缩功能不全。研究表明，自动控制系统通过在静止状态和真实动态循环系统中发生的某些瞬态过程中提供正常血液循环而有效发挥作用。
