    Abstract: The left ventricular blood pressure curve of one cardiac cycle of an actual heart is known, and its blood pressure curve is fitted by the fuzzy control of three elements. According to the characteristics at the time points on the curve of blood pressure, after divided into five sections, it could be fitted. When using a three-element-controlled fuz... Show More
