Summary of Expertise:
|
Listed with other top experts in: |
|
Expert has designed and taught courses on overall control theory, robust control, and optimal control. He has done research on crop growth chamber precision control, on VTOL supersonic aircraft robust control for transition to and from hover. Unique and unusual estimation and control experience includes bicycle stabilization, guidance, and remote control, tape drive speed control, and homing rocket optimal control.
|
|
|
He has designed and taught courses in electromechanical systems modeling, fluid mechanics and fluid systems modeling, thermodynamics and thermal systems modeling, instrumentation, the mathematics of dynamic systems, and interdisciplinary systems modeling.
|
|
|
He has designed and taught courses on estimation theory and uses the optimal stochastic estimation and control method on a regular basis. He has done definitive work in making parameter estimation by repeated integration maximally accurate, exposing and remedying many of the principal sources of error. He is experienced in applying the so-called maximum likelihood parameter estimation theory.
|
|
|
He is an expert in the use of the software MATLAB and MATHEMATICA for analysis and ACSL and SIMULINK for simulation. His experience in systems modeling, model analysis, and simulation includes: biosystems, including Monod food chain persistence, competition of Monod consumers, special resource consumption, and the Monod food web. While at the NASA Ames research center, he directed these capabilities to R&D in self-replicating peptide dynamics and to the population dynamics of the microbe Pseudomonas flourescens and systems of other microbes.
