Advancing Precision Motion Scanning Systems with the Prandtl-Ishlinskii Hysteresis Operator
The global research in micro-robotics, high-precision control, and modern mechatronic systems is expanding. Recently, high-precision positioning techniques have become widely used in several applications related to semiconductors, biomedical science, optics, haptics, and microscopy. Piezoelectric actuators can execute sub-nanometer moves at high frequencies because they derive their motion from solid-state crystalline effects. Indeed, manipulators driven by piezoelectric actuators have been commercially available, enabling us to discover reliable and practical control solutions that facilitate achieving high speed and position accuracy across a wide environmental range. As piezoelectric actuators serve as the manipulator’s actuators, the available control schemes for conventional robotic manipulators need to be re-investigated. Specifically, new real-world control schemes need to consider the hysteresis nonlinearities of these actuators. Non-smooth nonlinearities often severely limit system performance and accuracy. A significant example is piezoelectric actuators, which are finding numerous new applications in areas requiring high precision under various conditions. This motivates fundamental research into hysteresis estimation, identification, and control of general dynamic micro- and nanopositioning systems involving nonsmooth nonlinearities. The presentation will focus on estimation and control methods to stabilize smart micro/nano positioning systems within precision motion systems under high nonlinearities.
