Analysis of rudder instability during ship collision avoidance
In order to solve the problem of insufficient real-time control of rudder Angle during ship collision avoid-ance,the analysis method of rudder instability during ship collision avoidance is studied to ensure that ships can better adapt to environmental factors such as waves and ocean currents in complex and changeable sea conditions,and maintain the sta-bility of ship navigation.The input rudder Angle of ship collision avoidance is obtained by constructing the linear model of ship collision avoidance.Based on the ship linear model,a ship linear model containing time-varying delay in the course of ship collision avoidance is obtained,and combined with Lyapunov stability judgment theory,a ship linear model containing time-varying delay is obtained,which is unstable under the input rudder Angle,and the instability analysis of ship rudder during the course of ship collision avoidance is completed.Experimental results show that this method can effectively ana-lyze rudder instability during collision avoidance.After applying this method,the smoothness and stability of ship track dur-ing collision avoidance can be effectively improved,and the collision avoidance effect can be strengthened.
