In support of development of bioregenerative life support systems for space habitats, a chamber for conducting research on the biophysical response of crop plants in controlled environments is being designed by the National Aeronautics and Space Administration. The imprecision of mathematical descriptions of the behavior of biological systems led to the development of a model which can be used to...
Attention is directed to the problem of control robustness to the uncertain coefficient matrix of the plant disturbance vector for the case of a nominal linear representation. This issue is examined from the Lyapunov function gradient generated robustness enhancing control perspective. Conditions for robustness are presented, and the integration of these results into available results for the treating...
