Overview
abstract
The so-called signal-to-noise ratio is used to characterize instrumentation, and a system integration is achieved by jointly optimize the feedback control law and the instrument signal-to-noise ratios in order to meet system performance. The procedure identifies the performance limiting components of a control system, identifies where to spend money on a system, and generates component design requirements from closed loop performance. An example is included to illustrate how to use the theory developed here.
