Microfluidic droplet technique is a novel technology developed on the basis of microfluidics to study the formation, manipulation and application of microdroplets of a few micrometers size. It drastically enhances the advantages in terms of low consumption, automation and high throughput and is widely used in chemical, microelectronics, materials science, biology and biomedical engineering etc. Nevertheless, there are still a series of problems about the formation and control of droplet. To generate the given droplets and control their size, a micro-vibrator based cross-junction microfluidic system is designed and implemented, where the size of droplet can be dynamically adjusted via the flow rates of two phase fluids and the vibrant frequency of micro-vibrator. Moreover, a closed-loop control framework with certain special mothold, i.e., iterative learning control (ILC), is discussed to assist the formation of droplets. The experimental results confirm the feasibility of proposed scheme.
