Nano-precision Positioning, Control and Mechatronic Systems
Dr.
Kam Leang’s research passions are dynamic systems, control and
mechatronics design and theory. He also is passionate about teaching
and actively investigating new methods to enhance engineering
education. The key applications of his research include nano-precision
positioning systems and scanning probe microscope-based
bio/nanotechnologies. For example, Leang’s group concentrates on
developing state-of-the-art control techniques to achieve
nano-precision positioning of smart actuators, such as piezoactuators
and shape memory alloy devices, for atomic force microscopes. The work
embodies feedforward-based control techniques such as model-based
inversion, iterative learning control, and integrated feedback and
feedforward control. These methods consider the effects of hysteresis,
creep and vibration. Overcoming these issues enables the development of
high-performance technologies for research and commercial applications.
Specifically, the work is applied to AFM-based imaging and fabrication,
manipulation of biological samples and the development of biomedical
devices. For more information about Leang’s research, visit http://www.leang.com/research/.
