OPTIMUM SERVO PERFORMANCE IN A NOISE ENVIRONMENT

Abstract

A mathematical analysis is presented for Type I and Type II servo systems when subjected to a gated input consisting of a signal, plus random noise which is evenly distributed across the gate width. The analysis considers, in order, the response of Type I and Type II servos for signalonly input; the response of Type II servos for noise-only input; the response of Type I and Type II servos for signal-plus-noise input; and the derivation of probability equations. The probability is determined that, at any instant of time after the addition of the noise, the servo output (gate center) and the signal will be separated by more than one-half the gate width (resulting in a break in tracking). A procedure is given for choosing servo parameters minimize this probability. (Author)
