Nano-precision Positioning, Control and Mechatronic Systems

engineering building 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.
