Performance improvement of a DTG using an input compensator
Abstract
The rebalance loop of a dynamically Tunnel Gyroscope (DTG) is improved with the use of an 'input compensator' which compensates the disturbance effects of input rates, while the effect of the input compensator on the stability of the rebalance loop is negligible. Therefore, the input compensator and rebalance loop can be designed almost independently with each other. Experimental result on a DTG fabricated at Seoul National University (SNU-DTG) verifies the performance improvement. It is also shown that the input compensator can be applied to improve a single-degree-of-freedom (SDF) gyroscope.
