摘要: 针对混合动力船舶的模式切换过程中可能出现的扭转波动,传动轴剧烈冲击和离合器过度磨损问题,提出基于模型参考控制(MRC)的力矩协调控制策略。首先建立动力传动系统动力学模型,基于此推导出电机单独推进模式的动力学模型,并作为参考模型;然后设计MRC力矩协调控制策略。仿真结果表明,与传统的模式切换方式相比,MRC控制可改善动力中断和轴系剧烈冲击,而且显著减小离合器滑摩功。敏感性分析给出了外部干扰和执行机构噪声对控制品质的影响。

Abstract: During the mode transitions of the hybrid ships, unexpected torque fluctuations, intensive shaft jerk and clutch over wear tended to occur. A new torque coordination control method of MRC was proposed to address these problems. Dynamics models were built, followed by the reference model. The MRC algorithm was derived. The results show that compared with the conventional method, MRC may reduce power interruption and shafting dramatic impacts effectively. At the same time, the clutch friction loss is reduced evidently. Further, sensitivity analysis illustrates the effects of the external disturbances and the actuation noises on the transition performance.
