Taking advantage of the concurrent stretching and bending property corrugated flexure hinges, a sinusoidal linkage was proposed applied for construction dual-axial mechanism with structural symmetry decoupled planar motion guidance. Castigliano’s second theorem employed to derive complete compliance basic unit, matrix-based modeling then find stiffness mechanism. Using established analytical mo...

This work proposes two control feedback-feedforward algorithms, based on fuzzy logic in combination with neural networks, aimed at reducing the tracking error and improving actuation signal of piezoelectric actuators. These are frequently used devices a wide range applications due to their high precision micro- nanopositioning combined mechanical stiffness. Nevertheless, hysteresis is one main ...
