Cloud Model Based Intelligent Control for Marine Hydraulic Steering Gear System

Marine hydraulic steering gear is an important part of marine engine room system. Based on the analysis of the structure and mechanism of the marine hydraulic steering system, and combined with the modular modeling method, the mathematical model of marine hydraulic steering system, including system pipeline, hydraulic pump, steering gear and rudder angle controller is established. At the same time, a one-dimensional and two-dimensional cloud mathematical model, and a PD + I cloud model intelligent controller are designed and applied to control the marine hydraulic steering gear in this paper. The simulation results confirm that the cloud model based controller outperforms PID controller in terms of control stability and accuracy.
