Research on DP Ship Thrust Allocation Based on Improved Genetic Algorithm
For the non-convex constrained nonlinear optimization problem of DP ship thrust allocation,the optimization objective function considering thruster power consumption,wear and tear,and thrust allocation error is first established,taking into account the constraint inequalities due to thruster constraints.Moreover,the neighborhood search is introduced into the genetic algorithm to solve the defined thrust allocation optimization problem.The simulation results show that this algorithm has strong feasibility and accuracy for solving non-convex constrained nonlinear thrust allocation problems,which can effectively reduce propulsion system power con-sumptions and improve the ship dynamic positioning performance.
