摘要
以深水半潜式支持平台为研究对象,为提高靠泊效率对支持平台的航行轨迹进行优化。通过对平台航行过程中的相关分析,建立了平台的运动的模型,环境受力模型。并结合实际问题对相关参数进行约束和确定目标函数。运用伪谱法将最优控制问题转换成非线性规划问题去求解。仿真结果表明,伪谱法对求解支持平台的航迹优化有着良好的效果,能够满足相关的要求,具有一定的应用价值。
Taking deep-water semi submersible support platform as the research object,in order to improve the berthing efficiency,the navigation trajectory of the support platform is optimized.Through the relevant analysis of the platform navigation process,the model of the platform's motion and the environmental force model are established.And combined with the actual problem the relevant parameters are constrained and the objective function is determined.The pseudospectral method is used to transform the optimal control problem into a nonlinear programming problem.The simulation results show that the pseudospectral method has a good effect on the track optimization of the solution platform,which can meet the relevant requirements and has certain application value.
