Summary: | The invention discloses an autocorrection control method of pressure pulsation of an infusion pump. The control method comprises the steps that a motor operation step number A0 with minimum pressure pulsation is acquired by changing acceleration and deceleration positions of a motor; a corresponding compression coefficient C is calculated through a utilized solvent; the compression coefficient C is compared with a speed change position chart, and a corresponding speed change position formula is selected; an optimal relative speed change position A01 is calculated through the speed change position formula according to system pressure P; and differences among different instruments are corrected through a correction coefficient K, and a final optimal speed change position A is acquired, and Aequals to A01/K. According to a technology and the control method provided by the invention, automatic compensation is achieved within a relatively large pressure range, and relatively large pressurepulsation is generated du |
