➢ Project: Optimal Control-Based Bayesian Prediction of Seizure State Transitions ○ Utilized Bayesian theory with Markov Processes and Dynamic Programming to create a forward-backward scheme for seizure detection ○ Added probabilistic forward propagation of a Bayesian threshold function to change from detection to prediction ➢ Project: Optimization-Based Nonlinear Feedback Motion Planning for Deterministic Systems ○ Reformulated a Lyapunov function guessing problem into a nonlinear constrained optimization problem ○ Fixing the structure of the Lyapunov function and the nonlinear controller creates a set of minimization parameters ○ Created algorithms for subsampled state-space controller synthesis enabling nonlinear controller scheduling over a trajectory ➢ Project: Trajectory Optimization Using Nonlinear Controllers (In Progress) ○ Incorporating Rapidly Exploring Random Trees (RRTs) to fixed-structure controller optimization to optimize both the controller and trajectory ○ Deriving optimal control theory for high order expansions of the value function in finite time ○ Incorporating newly derived theory into DDP for optimization yielding nonlinear policies
