摘要
为了抑制船舶电力系统在周期电磁扰动下产生的混沌振荡,建立了船舶电力系统的双机并联数学模型,应用Melnikov方法得到了船舶电力系统产生混沌振荡的解析条件,采用输出延时反馈控制方法,通过选择合适的延迟时间和反馈系数,破坏系统发生混沌运动的参数条件.仿真结果表明,基于输出延时反馈控制方法的混沌控制器结构简单,所需的控制能量小,可以将系统的混沌运动状态控制为周期一运动,提高了船舶电力系统的稳定性.
In order to suppress chaotic vibration of ship electrical power system which was excited by periodic electromagnetism perturbation, twin-engine paralleling mathematical model was constructed and Melnikov method was applied to acquire the analytic condition of chaotic vibration. Output delay feedback idea was used to destroy such condition through selecting appropriate delay time and feedback coefficient. The simulation results show that the designed controller can restrain the chaotic oscillation into period one state with simple structure and less control energy that can enhance stability of ship electrical power system.
