Note (General): This paper reports on a method of reducing the interaction effect between the input and output peculiar to the Dynamically Tuned Dry Gyro (TDG), and the possibility of measuring angular accelerations about two axes, through improvements of the Rebalance Control Circuit (RCC) installed on the TDG. First, the design procedure and manufacture of the improved RCC which is necessary for noninteracting control are shown. Then, transfer functions of the TDG are derived, taking into consideration the manufacturing accuracy of the RCC, and each element of the RCC is examined analytically to see how relationships between inputs and outputs, and the reduction of interaction effect, are affected by its accuracy. Next, the frequency characteristics of direct and cross transfer functions are measured experimentally by applying electrical inputs to the TDG, and their characteristics are transformed into values equivalent to those for applied mechanical inputs. It has become evident after these experiments that the gain characteristics in cross transfer function, which correspond to the degree of reduction of the interaction effect, can be decreased remarkably without influencing the frequency characteristics of the direct transfer function, which prescribe the system performance of the TDG. Third, it is clarified that measurement of two-axis angular accelerations is realizable by scaling the outputs of the subtorquers which are newly introduced for noninteracting control. Finally, it is concluded from the analyses and experiments performed in this study that a fundamental concept of design and manufacture of the hardware of a noninteracting control system necessary for the development of future TDG’s with excellent performance has been established.
