摘要
针对以往操舵仪性能测评只关注控制精度,忽略不同操舵控制方法带来的能耗损失,对于操舵能耗测评,没有较为简洁通用的评价指标的问题,利用已有的船舶运动模型,推导舵阻力能耗近似求取公式,通过周期性摆舵仿真试验验证舵阻力能耗的影响,设计舵阻力能耗的评价指标,对比分析指标计算与周期性摆舵仿真试验结果表明,该舵阻力能耗评价指标与舵阻力能耗间有明确的对应关系,可作为在能耗方面评价操舵仪性能优劣的指标。
There is no simple and general evaluation index for steering energy consumption evaluation while too much attention is paid to control accuracy,ignoring the energy loss caused by different steering control methods.The existing MMG models were used to deduce the energy consumption of rudder resistance.And the impact of the energy consumption of rudder resistance was verified through the periodic rudder simulation test.An evaluation index of the rudder resistance energy consumption was designed.The comparison of the analysis index calculation and the periodic rudder simulation test results showed that there is a clear correspondence between the evaluation index and the rudder resistance energy consumption,which can be used as an index to evaluate the performance of the steering autopilot in terms of energy consumption.
