把整个浮桥系统作为研究对象,建立了分置式动力固定浮桥的动力学模型,按照动力固定控制系统设计要求对模型进行简化,将浮桥系统分为可控部分和不可控部分,针对可控部分,通过系统状态反馈进行模型解耦研究,考虑混合灵敏度问题,设计H∞鲁棒控制系统.仿真结果表明,所设计的动力固定控制系统能够有效地保持浮桥的可控桥节横向稳定性,即保证整个浮桥的横向稳定性,同时有效地抑制外界干扰.
Taking the whole pontoon system as the research object, the dynamic model of the split-type power fixed pontoon is established. According to the design requirements of the dynamic fixed control system, the model is simplified. The pontoon system is divided into the controllable part and the uncontrollable part, The model is decoupled by the system state feedback and the H∞ robust control system is designed considering the mixed sensitivity.The simulation results show that the designed dynamic fixed control system can effectively maintain the lateral stability of the controllable bridge section of pontoon, The lateral stability of the entire pontoon, while effectively inhibiting external interference.
