Feedback control performance over a noisy communication channel.\ud \ud

摘要

We consider the problem of minimizing the variance in the output of a plant that is driven by a Gaussian disturbance using measurements of the plant output obtained from a Gaussian channel. For the special case in which only the variance at the terminal time is penalized, we derive an optimal linear timevarying communication and control strategy, and argue that nonlinear strategies cannot achieve better performance.
