| Abstract: | The model of amplitude modulation atomic force microscope(AM-AFM) probe dynamic process is obtained by the Euler-Bernoulli equation.Based on AM-AFM's negative feedback control system with a PID controller,a simulation platform for AM-AFM is established.The simulation results show that the platform can accurately reflect the dynamic characteristic when the probe approaches and scans the sample.In consequence,for students doing the AM-AFM experiment,the platform can be used as an effective tool,which helps th... |
