Abstract
A method and apparatus for stabilizing relatively high-dynamics devices (e.g. a sight) mounted on a low-dynamics support such as a tank. Movement of the low-dynamics support is determined by means of an inertial central sensor block that may comprise a strapdown set of gyros or gyros and accelerometers. Stabilization is achieved by a two-step process in which the individual high-dynamics devices are stabilized with respect to the support by means of large bandwidth control loops. The much slower support movement is applied to a superposed loop of appropriately smaller band-width. Compensation thereby takes place by specifying a reference value for the control loops of the higher-dynamics devices.
