We consider the nonlinear, grey-box system identification problem. We establish an approximation of the covariance of a parameter estimate in this context, with several attractive theoretical properties. Our approximation is analogous to the inverse Fisher Information matrix, which approximates the covariance through the Cramer-Rao Lower bound. Indeed, it agrees asymptotically with the Cramer-Rao...
Reducing greenhouse gas emissions is now an important and pressing matter. Systems control theory, and in particular feedback control, can contribute to the design of policies that achieve sustainable levels of emissions of CO2 (and other greenhouse gases) while minimizing the impact on the economy, and at the same time explicitly addressing the high levels of uncertainty associated with predictions...
This paper investigates the chemotaxis behavior of the bacterium R. sphaeroides. We review the results of a recent study comparing different possible mathematical models of this bacterium's chemotaxis decision mechanisms. It was found that only one of the aforesaid models could explain the experimental chemotactic response data. From a control theoretic perspective, we show that, compared to the other...
