description: The subject of the graduate of qualification work is Â«Electro-hydraulic drive of the ship's steering machineÂ».The method of the graduate of qualification work is theoretical analysis and symbolic modeling.The given work is devoted to the design of an electro-hydraulic servo steering system of the ship's steering machine. The power stage of the automatic control system is a hydraulic drive with throttle control and constant pressure at the source. The actuating element is two double-acting hydraulic cylinders with a one-sided piston rod.Functional and schematic diagrams are constructed. To ensure the specified parameters, hydraulic equipment was selected. The static characteristics of the system are obtained.A dynamic calculation was carried out, during which the transfer functions of each component of the automatic control system of the ship's steering machine and the entire system were obtained. The quality factors for speed and acceleration, as well as the maximum drive error, are determined. The logarithmic amplitude-frequency characteristic and the logarithmic phase-frequency characteristic of the system are constructed.The original system was corrected by the method of successive correction to transform it into a more accurate and stable form. The transfer functions of the corrected system and the corrective device are obtained. The cutoff frequency of the open loop of the desired system was determined. The stability margins in amplitude and phase are determined.
