FIELD: control systems.
SUBSTANCE: invention relates to control method of hydraulically actuated drive unit (1–3), in particular, for valves, wherein at least on part of driving unit permutation path determining speed (v') permutation and is compared with a predetermined permutation speed (v), after which in case of difference between actual value (v') and set value (v) of speed of drive unit (1–3) is changed so that speed (v') of the drive unit permutation is reduced to the specified value (v).
EFFECT: technical result is invariable time of reinforcement irrespective of varying ambient temperatures.
