Abstract: Ship’s active maneuvering is carried out by the electrohydraulic (EH) drive of the steering gear. The maneuvering properties of the object completely depend on the proper operation of the drive control system. To move the rudder blade, it is necessary to regulate the change of oil flow from the pump to the steering gear, which is carried out by a special controlling device - a servomechanism. In order to obtain structural stability in the controlled and automatic modes of operation, feedback is provided by the servomotor, which in most cases is a short-circuited rotor motor. The main problem in creating an automatic control system/mechatronic system is the optimization of its structure and parameters taking into account certain criteria of the system components. It is possible to provide the regulation accuracy and energy efficiency automated electrical equipment by means of the control system “transvector” which is necessary for controlling the ship’s steering drives. The article represents the discussion about the effectiveness of using the “transvector” control system for a short-circuited rotor motor, and as a result it is possible to provide the ship’s steering mechatronic system with precise steering in the shortest possible time, which will minimize the ship’s deviation from the course.
