【摘要】 针对蠕动泵在微升级灌装过程中误差较大的问题，建立了电机驱动频率与目标容量的关系模型，并针对微升级灌装时出现的脉动和气泡的现象，提出了一种基于S型加减速曲线的误差补偿模型，并将该模型与无误差补偿的梯形加减速、抛物线加减速进行了仿真与实验验证。结果表明：灌装40μL时，相对精度分别提高了72%、57%；灌装100μL时，相对精度分别提高了73%、61%；灌装200μL时，相对精度分别提高了74%、62%，验证了所提方法的正确性和可行性。更多还原

【Abstract】 Aiming at the problem of large errors in the micro-upgrade filling process of peristaltic pumps,a relationship model between motor drive frequency and target volume was established,and an error compensation model based on S-shaped acceleration and deceleration curves was proposed for the phenomenon of pulsation and bubbles during microupgrade filling,and the model was simulated and experimentally verified with trapezoidal acceleration and deceleration and parabolic acceleration and deceleration without error compensation. The experimental results show that the relative accuracy is improved by 72% and 57% for filling 40 μL,73% and 61% for filling 100 μL and 74% and 62% for filling 200 μL,respectively,which verifies the correctness and feasibility of the proposed method.更多还原
