题目：High-Speed Imaging and Broadband Nanomechanical Quantification on Scanning Probe Microscope: A Learning-Control-based Approach

Abstract：Scanning probe microscope (SPM) has become the enabling tool to image, characterize, modify, and manipulate a wide spectrum of materials at nano- to atomic scale. However, due to its serial operation nature, SPM has been limited in its imaging speed to interrogate dynamic phenomena at nanoscale and molecular level, as well as the frequency range of nanomechanicalmeasurementto quantitatively characterizetheevolutions of material properties during dynamic processes occurring in seconds or even faster. These challenges exist due to factors including the excitation of the intertwined dynamics and hysteresis effects of piezoelectric actuators, the nonlinear probe-sample interaction dynamics, the distributive hydrodynamic disturbance force, and the need of applied force to rapidly excite the material properties (not others). In this talk, I will present a suite of inversion-based iterative-learning- control (ILC) tools to achievehigh-speed SPM imaging, rapid broadband nanomechanical quantifications of soft and live biological materials, and high-speed probe-based nanofabrication. Then I will conclude the talk by discussing our recent efforts in extending the ILC beyond repetitive applications by combining offlinea priori learning via ILC with online synthesis, first, for linear systems, and then, for simultaneous hysteresis-dynamics compensation in systems such as smart actuators.
