Research

Nonlinear Estimation
To prepare for future research involving fault detection, I am currently studying probability, Bayesian estimation, and sequential Monte Carlo methods.
Nonlinear Systems
Estimation of the region of attraction for nonlinear systems using sum of squares (SOS) programming techniques. Automated generation of Lyapunov functions for stability analysis and control.
Local Gain Analysis
Numerical techniques to provide a lower bound on the "worst case" performance of nonlinear systems by approximating performance measures such as the local "L2-to-L2" gain.
See research for more information (includes undergraduate projects).
