摘　　要：针对船舶综合电力系统在高机动工况下多电机驱动负载剧烈变化及机械同步轴扭振问题,本研究提出了一种基于“速度环+力矩均衡控制策略”的多电机机械同轴力矩均衡与振动抑制优化方案。该方案通过为每套传动装置设置速度环和转矩环,结合负荷均衡调节器补偿主、从传动装置间的转矩差值,同时在电流闭环中引入速度前馈、转矩补偿、预加力矩和平均速度阻尼等技术,实现了对同步轴系统轴扭振的有效抑制和多电机负载的均衡分配。仿真验证表明,该优化策略在升平台工况下显著提高了系统对扰动的快速响应能力,为船舶综合电力系统复杂工况下的高机动特性优化提供了理论支撑和实践依据。To address the problems of severe load fluctuations and torsional vibrations in the mechanical synchronous shaft under high-mobility operating conditions of ship-integrated electric propulsion systems,this study proposes an optimization scheme for multi-motor mechanical coaxial torque balance and vibration suppression based on the"speed loop+torque balancing control strategy."The scheme involves setting up speed and torque loops for each transmission device,using a load balancing regulator to compensate for the torque differences between the master and slave transmission devices.In addition,techniques such as speed feed forward,torque compensation,pre-applied torque,and average speed damping are introduced into the current control loop to effectively suppress torsional vibrations in the synchronous shaft system and achieve balanced load distribution across multiple motors.Simulation results demonstrate that the proposed strategy significantly improves the system’s rapid response to disturbances under lifting platform conditions,providing theoretical support and practical guidance for optimizing the high-mobility characteristics of ship-integrated electric propulsion systems under complex operating conditions.
