Controllability, Observability, Realizability, and Stability of Dynamic Linear Systems
John M. Davis, Ian A. Gravagne, Billy J. Jackson +1
We develop a linear systems theory that coincides with the existing theories for continuous and discrete dynamical systems, but that also extends to linear systems defined on nonun…

A Unified Approach to High-Gain Adaptive Controllers
Ian A. Gravagne, John M. Davis, Jeffrey J. DaCunha
It has been known for some time that proportional output feedback will stabilize MIMO, minimum-phase, linear time-invariant systems if the feedback gain is sufficiently large. High…
