An Analysis of DREO's (Defence Research Establishment Ottawa) Analog Rebalance Loops for the CSG-2 (Canadian Strapdown Gyroscope) Tuned-Rotor Gyroscope

Abstract

A high performance analog rebalance loop was designed for the Canadian Strapdown Gyroscope (CSG-2). This instrument is a potentially low cost, near inertial grade, two degree-of-freedom, tuned-rotor gyro designed and manufactured by Litton Systems Canada Ltd. under contract to DREO. The resulting loops are analyzed extensively from a control systems point of view with the examination of such properties as closed-loop stability, frequency and time responses and, to some extent, stability margin, as interpreted from multivariable generalizations of classical control-theoretic notions of Nyguist plots and root locii. The results indicate that the loops will provide sufficient closed loop performance to achieve the desired goals of bandwidth, maximum input rate, low cross-axis coupling and acceleration compensation.
