Abstract


The drive control system is a for microfluidic digital technology in the various applications to important device system . The of microfluidic digital technology applications continues to expand the drive control system miniaturization , independence and stability requirements . Based on the experimental phenomenon analysis and verify the pulse hopping signals with micro- injection effect relationship . The proposed microfluidic digital technology based on specific design requirements of the control system with a piezoelectric drive . Developed miniaturization , PC - independent , high stability , easy to upgrade the piezoelectric drive control system design , and proposed to meet the a microfluidic digital technology needs , the AWG technology - based signal synthesis scheme . FPGA design platform based on SOPC technology embedded signal controller hardware circuit and the PCB Nios Ⅱ soft -core processor the SOPC module and rotation mode control system software framework is designed , produced and debugging success signal control a circuit . At the same time , through the trial of the program , the testing and improvement, designed and fabricated a chip piezoelectric drive power PA93 -based integrated power amplifier module . After various tests , system control functions and driving performance parameters are in line with the requirements of the intended design . Microfluidic digital applications Experiments show that good control performance of the system drive , be able to meet your application needs . Finally , miniaturization characteristics , combined with the drive control system designed micro- propulsion experiment system based on microfluidic digital technology microsatellite attitude adjustment . Experimental results show that the micro- propulsion experiment system can realize satisfied Newton's second order micro - impulse , to explore a new way to achieve high-precision attitude adjustment tiny satellite .
