A Primer on Pontryagin's Principle in Optimal Control
I.  Michael Ross is a Professor and Program Director of Control and Optimization at the Naval Postgraduate School.  A Fellow of the AAS, he is the author of DIDO (http://www.ElissarGlobal.com), the world's #1 software for solving optimal control problems. In 2006, NASA used DIDO to successfully maneuver the International Space Station in an optimal manner - zero fuel! In 2010, Ross received the AIAA Mechanics and Control of Flight for "changing the landscape of flight mechanics."  His research contributions to pseudospectral optimal control theory have been translated to Russian, German, Chinese and Japanese and are taught at universities in US, Europe and Asia. A Founding Book Review Editor for the Journal of Guidance, Control and Dynamics, Ross consults for businesses in aerospace engineering, chemical engineering, and energy harvesting in the areas of optimal control theory and computation.
