Dr. Parker
specializes in control system design and methods for correlating
nonlinear dynamic models to experimental data. An emerging area
of research is the utilization of interspacecraft Coulomb forces
for both position and attitude control. This has applications from
spacecraft formation flying to active “virtual” structures
that are highly reconfigurable and robust to individual spacecraft
failure. Spacecraft force coupling and the nonlinear electrostatic
force behavior provide a variety of interesting technical challenges
from nonlinear control to optimal formation design. Similar research
topic areas such as, nonlinear control, system simulation, nonlinear
system parameter identification and optimization, are present in
most of his ongoing projects. Examples include active control of
diesel engine aftertreatment systems, at-sea ship crane control,
and hydraulic system parameter identification. Another research
area is focused on increasing robot-based, flexible material throughput
for manufacturing
applications. The system dynamics of the part are exploited, in
conjunction with vision-based trajectory optimization, to minimize
maneuver time.
