With the recent progress in on-board digital computer technology in this country, digital inertial instruments such as digital gyros and digital accelerometers are required for accomplishment of precise inertial navigation system. A digital accelerometer equipment is developed at NAL using delta-modulation technique. The equipment is a combination of a floated pendulum accelerometer and a digital servo-amplifier which involves sampling and a two-level relay. The control is a so-called bang-bang. This report describes the principle, configuration, analyses, design and experiments of the digital accelerometer equipment. The stress is laid on the analyses of the stability and modes of the limit cycle particularly when an input acceleration is relatively large. According to the analyses using dual-input describing function theory, the limit cycle is always stable if only the input acceleration is less than the maximum input; however, as input acceleration becomes very close to the maximum, the limit cycle frequency approaches zero and at the same time the amplitude of the limit cycle oscillation becomes large. This results in worse transient response and in increased static error. The analyses are compared with the experiments, and“a precision input range of the pulse-rebalanced accelerometer”, where both response time and static error are very small, is determined. |
