METHOD OF SHIP COORDINATED MANEUVERING Russian patent published in 2011 - IPC B63H25/04 G05D1/02 

FIELD: transport.

SUBSTANCE: invention may me used at river-marine ships operated in inland waters using vertical rudders (VR) and propulsive complex (PC) , limited navigation complex made up of log, ship turn speed indicator and ship location receiver-indicators. Ship side drift mismatch signals, ship desirable speeds in sailing along preset trajectory, ship speed mismatch magnitudes, course mismatch signals, those in rudder deflection in sailing along circle arc, those in rudder deflection in midplane are processed to generate VR control signal to minimise course and lateral drift mismatch. In rudder deflection in sailing along circle arc to minimise course and lateral drift speed VR control signal is fed to first input of VR LCS with its second input receiving signal from VR deflection angle feedback transducer while output signal from VR LCS is fed to ship VR actuator drive unit connected with VR deflection angle feedback transducer. PC control unit processes ship speed mismatch signal to generate ship speed control signal to be fed to VR LCS unit input while VR LCS second input receives rpm feedback transducer. Output signal of VR LCS is fed to PC actuator drive unit connected with water propeller rpm transducer. Note here that visual control over turn speed is performed using turn speed indicator.

EFFECT: speed and course control observing preset parameters of maneuvering.
