    Frequency modulation of an atomic force microscope is based on a PI control law, which keeps the amplitude equal to a desired value. This paper analyses the stability and performance of the closed-loop nonlinear dynamics of AFM. Numerical results are presented to corroborate the validity of theoretical analysis.
