{"cited_by_count":248062,"description":"This cluster of papers focuses on the modeling, identification, and control of hysteresis and creep in nanopositioning systems, particularly utilizing piezoelectric actuators and flexure-based mechanisms. The research addresses challenges related to high-speed micro/nanomanipulation, feedback control strategies, and the development of smart actuators for precise positioning.","display_name":"Piezoelectric Actuators and
