Features of control system upgrade of the group hydraulic drive of navigable hydrotechnical facilities

The group hydraulic drive with automated system of frequency-throttle control of gateway of navigable hydrotechnical facilities in case of considerable mass, hydrodynamic and tribotechnical loads of rods of hydraulic cylinders is developed. Operability of hydraulic drive with frequency and throttle control system by results of successful code proposed navigation in 2013-2015 is confirmed. Extreme values of distortions of lifting and lowering gate with a length of 30 meters made no more than 12 mm in case of admissible value of 60 mm.
