,A Review of Stick–Slip Nanopositioning Actuators, resolution and long travel distances. These actuators, termed PSTA (piezoelectric stick–slip actuators), are widely used in chip assembly and cell manipulation. This chapter provides a comprehensive review of PSTA systems. Reported PSTAs are generalized with two specific principles which can be con

Parallel-Kinematic Nanopositioning Stages Based on Roberts Mechanism,nism, the design of multi-axis parallel compliant stage is synthesized. A new XY nanopositioning stage is studied in detail. Pseudo-rigid-body model (PRBM) is developed to build the quantitative models of the compliant Roberts mechanisms. In addition, finite-element analysis (FEA) is carried out to

Tracking Control for Nanopositioning Systems,ion, hysteresis, and creep can drastically limit positioning precision. Therefore, tracking control, both feedback and feedforward control, plays an important role in achieving high-performance operation, especially at high operating frequencies. This chapter reviews popular feedback and feedforward
