STEERING ELECTRIC SERVO DRIVE Russian patent published in 2010 - IPC F42B15/01 

FIELD: weapons and ammunition.

SUBSTANCE: to expand bandwidth, allow abrupt amplitude-frequency roll-off on frequencies above bandwidth and ensure low phase delay in bandwidth at high and low input signal amplitudes, proposed servo drive comprises first and second adders, first and second LF-filters, reference model unit, first comparator, power amplifier, actuator motor, reduction gear and feedback transducer, first limiter and first differentiator. It comprises also speed transducer, second comparator, 2^nd, 3^rd and 4^th differentiators, 3^rd, 4^th, 5^th and 6^th adders, 1^st and 2^nd dividers, speed controller, 2^nd limiter, engine model unit, 3^rd, 4^th, 5^th and 6^th LF-filters, 1^st and 2^nd modulus selection devices, 1^st and 2^nd logic devices and functional transducer.

EFFECT: improved dynamic characteristics.
