ABSTRACT:
A system for interfacing a digital computer with an analog gimbal control loop rate integrating gyro for controlling the movement of inner and outer gimbaled elements is disclosed. The purpose of the interface system is to permit an increase in the agility of the analog control loop without imposing unreasonable data rate requirements on the digital computer. In operation, the digital computer generates a rate command signal which is stepwise updated at designated time intervals and provided to the analog gimbal control loop to govern the rate output thereof. The interface system, which includes an element for filtering the rate command signal which governs the analog gimbal control loop, an element for generating a feed-forward aiding signal as a function of the rate of change of the filtered rate command signal to further govern the analog gimbal control loop, and an element for compensating the rate command signal for the operation of the filtering process to render the average rate output of the analog gimbal control loop during the time intervals between computer rate command signal updates to be substantially that desired.
