针对船载多参数拖曳式剖面测量系统,进行了自适应追踪等温层研究.根据拖缆和拖曳体的理论模型,利用海上拖曳试验数据优化3个重要水动力参数,构建了该拖曳系统的半分析(半解析)运动模型.依据感知-决策-执行-反馈的回路控制思路,在实测数据插值的温度场中,模拟拖曳系统运行,利用感知的温度与等温层的温度偏差,自适应给出拖曳体的期望深度;根据拖曳系统的半分析运动模型,利用PI控制算法对该期望深度进行响应,实现追踪等温层.以26.5℃等温层为例,给出了追踪数值算例.
Isothermal layer's adaptive tracking was studied for shipboard towed muti-parameters profile sampling system.Based on the theoretical model of cable and towed body,three important hydrodynamic parameters were optimized using towed data from sea trials,and a semi-analytical physical model of towed system was constructed.According to the idea of sensing-deciding-acting-feedback,the operation of the towed system was simulated in the field of temperature data from interpolated towed sampling.By using the differ...
