船舶主机气囊隔振系统对中控制的响应特性分析及算法研究

摘要

The influence of air spring pressure variation on a main engine alignment was analyzed with an established model. Results showed that the alignment calculation model can be linearized within a certain pressure range. The error induced by this linearization was analyzed. A simplified optimization control algorithm for alignment was presented based on the analysis. The test results showed that the linearized model and the control algorithm are effective.%分析了气囊隔振装置的压力变化对主机对中姿态的影响,认为主机姿态控制的响应计算可进行线性化处理,并给出了满足线性计算精度要求的压力变化范围.在此基础上,提出一种新的优化控制算法,将气囊压力分布与对中姿态同时作为控制目标.在试验台架上验证了理论分析的正确性,控制算法使气囊压力与对中姿态两个指标均能快速收敛到精度范围,具有较高的控制精度.
