船舶建模新方法研究

Study on New Method to Control Model of Ship

根据舰船横向运动的水动力模型 ,讨论了将水动力模型化为一个仅随舰船的航向、航速变化 ,而与频率无关的控制模型的几种方法 ,运用微分方程最小二乘拟合法产生了船舶的控制模型 ,并对其幅相特性、能控能观性及稳定性加以验证 。

Discusses several methods to control hydrodynamic model into a control model which only change with heading and speed and have no relation with frequency. By using least square fit of differential equation, the shipping control model is acquired, and the gain phase characteristic, the controllability and observability and the stability are proven. Simulation results indicate that this control model is reasonable.
