摘要
以舵减摇的线性模型为研究对象,采用滑模变结构控制设计出舵减摇控制器,并在保证减摇效果的前提下,利用模糊逻辑算法对所设计切换函数的参数进行在线调整和优化,使得调整后的切换函数更合理,由于控制量与切换函数相关,从而使得控制量的输出减小,达到降低舵机摩擦损耗的目的,仿真研究表明该方法的有效性。
Based on a ship roll movement liner dynamics model, a rudder roll damping controller is designed by sliding mode variable structure control method, then adjust and optimize the parameters of the switch function designed above with fuzzy logic arithmetic, which would get the switch function more reasonable, thus decrease the control variable indirectly be cause of the correlation between control variable and switch function, which angle for reducing the rudder attrition. Simulation results prove the effectiveness of the proposed method.
