在本研究中，我们推导了低压级联电渗微型泵的高效降阶模型。该模型可以与直微通道的等效电路模型相结合，构建微流控装置的完整模型，可用于实现现代控制方案。为了证明降阶模型的效率，我们利用速度测量来估计微泵级联中许多子通道的 zeta 电位，这是实施现代控制方案的第一步。研究发现，采用降阶模型的共轭梯度程序可以准确估计子通道中的 zeta 电位变化，这可能是由生物分子粘附引起的，即使速度测量存在噪声。
In the present investigation, we have derived an efficient reduced-order model of the low-voltage cascade electroosmotic micropump. This model can be combined with the equivalent circuit model of straight microchannels to construct a complete model for a microfluidic device, which can be employed to implement modern control schemes. To demonstrate the efficiency of the reduced-order model we employ it to estimate the zeta potentials of many subchannels in the micropump cascade using velocity measurements, which is a preliminary step to the implementation of modern control schemes. It is found that a conjugate gradient procedure employing the reduced-order model estimates accurately the zeta potential variation in the subchannels, which may be caused by adhesion of biomolecules, even with noisy velocity measurements.
