Professor Messner's research emphasis application of linear and nonlinear control to robotics, data storage systems, and most recently in biological research. Two specialties are devising insightful and user friendly methods for controller design and identifying and compensating for nonlinear dynamics in control systems.
Professor Messner and his students work projects relating to control issues in data storage systems and robotics. Data storage projects include (1) compensation for nonlinear friction dynamics in disk drive rotary actuators to improve servo performance at very high data track densities (more than 150,000 tracks per inch), (2) active tape steering control to eliminate the need for guide flanges in tape drives employing extremely thin tape (3 micron) for a 10 terabit capacity tape drive, and (3) an electrothermal rotary microactuator for skew compensation for disk drives.
Professor Messner's work on robotics has included highly distributed manipulation using a planar array of actuators, obstacle avoidance for manipulator arms, flight control of unmanned helicopters, and the unmanned ground vehicles for the DARPA Grand Challenge. Work on the CMU/Yamaha R50 led record setting performance for that platform.
In the bio area, Professor Messner is collaborating with his colleague Dr. Phil Leduc to design and build a new instrument for probing cellular mechanics using microfluidics, mechatronics, and computer vision. The goal is the abilitiy to acquire high quality time series data of cells for black box or grey box system identification.
Professor Messner is a Fellow of the AAAS, a Fellow of the ASME, and a Senior Member of IEEE.
