Automatic control algorithm for ship heading stability considering lateral wind and wave interference
Considering the lateral wind and wave interference,the ship entering the roll motion state is prone to deviate from the expected heading trajectory.Therefore,a ship heading stability automatic control algorithm considering the lateral wind and wave interference is studied.After modeling the ship's rudder and lateral wind and wave interference,this al-gorithm inputs the expected heading parameters into the heading controller based on the mastered ship's rudder control para-meters and interference intensity.Under the improved BP-PID algorithm based heading stability automatic control scheme,the improved BP neural network adjusts the PID controller parameters and outputs the rudder angle and speed adjustment proportional coefficients that meet the expected heading conditions Differential and integral coefficients are used to adjust the heading and achieve automatic control of heading stability.In the experiment,under lateral wind and wave interference,using this algorithm to control the ship's heading significantly reduced the mean squared deviation of bow roll angle,roll angle,and fin angle during navigation,indicating that the algorithm can control the ship to navigate steadily according to the desired heading.
