中文摘要
      针对存在扰动的一维人群动态系统, 在扩散系数及边界条件系数未知的情况下, 设计自适应边界控制律来控制人群向设定的方向平稳疏散. 借助李雅普诺夫稳态判据对自适应边界控制作用下的人群动态系统的稳定性给出了详细的证明. 系统的建模及稳定性的证明均在分布参数系统的范畴内完成, 避免了模型降阶方法引起的误差的产生. 通过一个仿真实例, 对比不同扩散系数取值时的人群动态系统在未加控制与自适应边界控制作用下的人群密度演化, 验证了自适应边界控制律的有效性.
英文摘要
      For a one dimensional crowd dynamic system with disturbance, the adaptive boundary control law is designed to control the crowd to smoothly evacuate in the set direction when the diffusion coefficient and the boundary condition coefficient are unknown. The stability of the crowd dynamic system under adaptive boundary control is proved in detail by means of the Lyapunov method. The modeling of the system and the proof of stability are all done within the scope of the distributed parameter system, avoiding errors caused by the model reduction. Through a simulation example, the density of crowd dynamic systems under uncontrolled and adaptive boundary control are compared to verify the efficiency of adaptive boundary control law.
