摘要: 本文对人体血液循环系统的数学模型进行了讨论,得出了其矩阵表达形式.在此基础上, 介绍了将人工心脏作为左心室辅助心室的双输入、双输出自适应控制系统.系统采用微型机 在线识别和自调整PID控制.多次实验结果表明.这种控制方案是有效的、可行的.Abstract: In this paper, the mathematical model of blood circulatory system is discussed and a compact matrix form of this model is given. Then a microcomputer-based two-input two-output adaptive control system for left ventricular bypass assist devices is presented. The system design includes an adaptive control algorithm with on-line identification and self-adjustment PID control. Many experiments show that this adaptive control is feasible and suitable.
