ABSTRACT:
A rotatable member, such as a turret at a weapons station, is controllable about an azimuth axis. A weapon is carried in the turret with the weapon being controllable therewithin about an elevation axis. The moments of inertia of the turret and weapon about the azimuth axis and of the weapon about the elevation axis are relatively high. The disclosed system provides for elevation and azimuth control through elevation and azimuth drive trains having reflected drive train inertias which are at least two orders of magnitude smaller than the inertia of the turret and weapon about the azimuth axis and at least one order of magnitude smaller than the inertia of the weapon about the elevation axis. Further, the system senses spurious torque applied about either axis, as for example due to the recoil of the fixed weapon, and provides automatic repositioning of the controlled members about either axis to compensate for angular displacement caused by the spurious torque.
