摘要
本文用生物伯德图分析了血压稳定性。按照经典的控制理论,讨论了生物系统的稳定性,提出了血压控制的数学模型。根据生物特点,建立了生物伯德图的表达式。作为系统稳定性的指标,增益裕量和相位裕量可以用作图法求得,也可以用计算机求解。实验结果与理论分析能很好地符合。
The stability of blood pressure was analyzed by Bio-Bode diagram. The stability of biological system was discussed based on classic automatic control system and a mathematic model of blood pressure control was presented. The expression of Bio-Bode diagram was established according to biological features. Gain margin, phase margin and symboles of the stability of the system could be obtained either by diagram or by compute and the results of experiment were well coincided with theoretical analysis.
