摘要
基于升力反馈控制减摇鳍系统,分析升力测量原理及所存在的非线性特性,并在升力控制减摇鳍伺服系统中采用升力/鳍角综合控制减摇鳍控制方法,修正升力反馈信号的检测问题.构建基于小波降噪的数据融合模型,该模型综合升力、鳍角传感器不同频带信息,消除信息之间的冗余和矛盾,利用信息之间的互补来获得对升力信号相对完整一致的描述.仿真结果表明,应用数据融合模型的控制系统在各种海况下均可达到良好平稳的减摇效果.
The principle of measurement and nonlinearity of lift force were analyzed based on the lift fin stabilizer system,and fin-lift/fin-angle integrated control method was adopted in the servo system of fin stabilizers with lift force feedback control,which could modify the lift force feedback detection signal.The data fusion model was built based on wavelet denoising algorithm,the different bandwidth information from the lift force and fin angle sensors were integrated to smooth out the redundancy and contradiction information.So the comparatively integrated lift force signal was obtained by using complementary action of all information.Simulation results demonstrates the good anti-rolling performance by employing the data fusion model in control system under all sea conditions.
