High-Precision Control of a Piezo-Driven Nanopositioner Using Fuzzy Logic Controllers

This paper presents single- and dual-loop fuzzy control schemes to precisely control the piezo-driven nanopositioner in the x- and y-axis directions. Various issues are associated with this control problem, such as low stability margin due to the sharp resonant peak, nonlinear dynamics, parameter un...
