California, Irvine
The problem of globally stabilizing the attitude of a rigid body was
considered. Topological and geometric properties of the space of
rotations relevant to the stabilization problem were investigated. A
control Lyapunov function approach was used to design globally
stabilizing feedback laws that have desirable optimality
properties. Their performance was compared to the performance of
previously developed proportional-derivative and feedback linearizing
control laws and shown to be superior.
X-34 Entry Guidance.
Joint work with
Prof. Kenneth D. Mease, University of
California, Irvine
The entry corridor was computed for X-34 aerodynamic model.
For the reduced order model of the X-34 vehicle 3D predictive
guidance/trajectory planner was generated as a solution of optimal
control problem with constraints.
Ejection Seat Flight Optimizer.
Joint work with
Prof. Kenneth D. Mease, University of
California, Irvine
The ejection seat/pilot system was modeled as a six-degree of freedom
rigid body. For the model predictive guidance the set of feasible
trajectories was generated as a solution of the optimal control
problem with constraints on control input and state variables imposed
by safe crew escape requirements.
