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, 2nd, 3rd and 4th differentiators, 3rd, 4th, 5th and 6th adders, 1st and 2nd dividers, speed controller, 2nd limiter, engine model unit, 3rd, 4th, 5th and 6th LF-filters, 1st and 2nd modulus selection devices, 1st and 2nd logic devices and functional transducer. ^ EFFECT: improved dynamic characteristics. ^ 5 dwg |
