Abstract:
This thesis addresses the critical issue of resolver signal demodulation in the gun control
system (GCS) of military battle tanks (MBTs). The GCS is responsible for two crucial
functions: moving the gun in both azimuth and elevation based on signals from the gunner,
and stabilizing the gun in bi-axes when the tank is in motion or on uneven terrain. To
achieve these functions, the GCS requires an accurate and reliable resolver signal
demodulation technique.
Existing electronic amplifier techniques used in MBTs for translating console signals have
become obsolete and their performance has been compromised. Therefore, a new and
innovative technique for resolver signal demodulation in MBT GCS, Phase Sensitive
Demodulation (PSD), has been proposed in this thesis. The PSD technique offers the same
performance criteria as existing techniques, but at a significantly lower cost. To determine
the most efficient and cost-effective solution, this thesis compares different techniques
used for evaluating resolver signals. In-house and on-system tests are conducted to
validate the proposed PSD technique. Even though the proposed technique does not
compromise on performance, the results demonstrate that it provides a cost-effective
solution for resolver signal demodulation in MBT GCS. With no significant changes to
the existing GCS, the new technique can be easily incorporated into future MBTs.
By proposing a new and cost-effective technique for resolver signal demodulation, this
thesis makes an important contribution to the field of MBT GCS technology. In addition
to improving the overall performance of MBT GCS, the proposed technique may also
contribute to its reliability, which is a critical factor for military operations to be
successful.
