Optimal Control for a Two Player Dynamic Pursuit Evasion Game; The Herding Problem
… is proposed, analyzed and we came up with an optimal control law for the pursuer is obtained so that the evader is driven to the desired destination position in the x-y grid following the local shortest path in the Euler Lagrange sense. Then, a non-holonomic realization of the two agents is …

Optimal feedback control for nonlinear discrete systems and applications to optimal control of nonlinear periodic ordinary differential equations
This dissertation presents a discussion of the optimal feedback control for nonliner systems (both discrete and ODE) and nonquadratic cost functions in order to achieve improved performance and larger regions of asymptotic stability in the nonlinear system context. The main work of this thesis is …

Dynamics and control of a planar truss actuator
… technology have suggested the use of active control actuators integral to a structures' construction. The concept of a 3-D (triangular cross-sectioned) active truss is presented. The linear equations of motion for one plane of the truss are derived. A model for a generic flexible beam is then …

Nonlinear optimal control and near-optimal guidance strategies in spacecraft general attitude maneuvers
Solving the optimal open-loop control problems for spacecraft large-angle attitude maneuvers generally requires the use of numerical techniques whose reliability is strongly case dependent. The primary goal of this dissertation is to increase the solution reliability of the associated nonlinear …

Nonlinear Dynamics Analysis and Control of Space Vehicles with Flexible Structures
… the system dynamics for stability analysis and control design. The system model is represented by a flexible appendage attached to a central rigid body, where the flexible appendage is modeled as a cantilevered Euler-Bernoulli beam. Discretization techniques, such as the assumed modes method and …

Uncertainty, complication and optimal model construction
"I consider the problem of determining optimal knowledge partitions in problems described by complicated models with associated embedded optimization requirements. The particular models studied are linear control models in which the embedded optimization is that of observer/ controller design. The …
