ABSTRACT
Based on a system approach and performance analysis of ship power plant combined propulsion system of dynamically positioning oil-producing vessel, taking into account the restrictions on the power and torque on the shaft, as well as various control strategies thrusters the mathematical model of all-range speed controller has been developed. The mathematical models and transfer functions are obtained, and flowcharts of closed systems regulating speed, torque and power steering device are developed, depending on the dynamic characteristics of the vessel under the influence of instability of screws and environmental conditions. Based on the developed environment MatLab/Simulink simulation model of all-range speed controller for a test case the simulation results were obtained, when automatic control transfer from one mode to another is observed, depending on the operating conditions.
