ABSTRACT

In this paper, the basic principle and calculation method of geostrophic deflection force are deeply understood by combining theoretical derivation, mathematical modeling, numerical simulation and simulation verification. The mathematical model of ship yaw based on geostrophic deflection force is established and solved by mathematical software. Using numerical simulation and simulation technology, the influence law of geostrophic deflection force on ship yaw is studied. A ship yaw control strategy based on geostrophic deflection force is designed and verified by simulation. The research method combining mathematical modeling and simulation verification can not only reveal the action mechanism of geostrophic deflection force, but also provide guidance for the design and optimization of control strategy. The research shows that the ship yaw control strategy proposed in this paper is highly effective and feasible, and can provide theoretical support and practical guidance for ship yaw control in actual navigation. At the same time, this strategy also provides new ideas and methods for the design and optimization of ship control system in the future. Therefore, this strategy has important research significance and application value.
