Stability, Aim Bias Compensation and Noise Sensitivity of Phalanx Ciws Control System

An aiming control system which is similar to that in the Block I PHALANX CIWS is considered in this report. An important feature of this control system is that it compensates for any gun aim bias. An aim bias may be caused by variations in the gun, ammunition or environmental conditions. Design issues considered are stability, aim bias compensation and sensitivity to feedback noise. These are disparate design goals. Design tradeoffs which quantify this disparity are presented.
