【摘要】A novel nano-measurement system based on dual Fabry-Perotinterferometer is designed and a mathematical model for various links of the system is described.In accordance with the characteristics that the mathematical model for the mutual action between probe and sample surface is complicated,a control system based on fuzzy control theory is designed.Some theoretical basis and practical measurement method for carrying out nano-measurement through control curve central line of probe vibration is proposed.Simulation experiments for the system are carried out on this basis.The experimental results fully demonstrate the correctness of system and theoretical basis.%设计了一种基于双Fabry-Perot干涉仪的新型纳米测量系统,阐述了系统各环节的数学模型。针对探针与样品表面相互作用的数学模型比较复杂的特点,详细设计了基于模糊控制理论的控制系统,提出了通过控制探针振动曲线中线不变进行纳米测量的理论依据及实测方法。在此基础上,对系统进行了仿真实验,实验结果充分证明了系统设计及理论依据的正确性。 【总页数】7页(43-49)
