对地面夯实机构简化为机座安装在弹性支撑上的偏心转子的混沌运动和混沌控制问题进行了研究。研究表明,随着偏心质量的等效转子转动角速度的增加,系统经历了由倍周期分岔进入混沌,再由混沌到周期的运动状态演变过程。为控制系统的混沌运动,提出了基于混沌边缘确定控制器的设计参数的方法。方法的核心是将控制器的设计参数作为系统的参数,确定出系统的混沌边缘,由系统的混沌边缘直接确定出控制器的设计参数。以比例—微分控制器和相位控制器的设计说明了提出方法的具体步骤和有效性。
The problem of chaos and chaos control of the ground compaction mechanism simplified as the eccentric rotor mounted on the elastic support was studied. The results show that with the increase of the angular velocity of equivalent rotor with eccentric mass, the system experiences the evolution from the bifurcation bifurcation into the chaos, and then from the chaos to the period. To control the chaotic motion of the system, a method of determining the design parameters of the controller based on the chaotic edge is proposed. The core of the method is to use the design parameters of the controller as the parameters of the system to determine the chaos edge of the system, and the design parameters of the controller are directly determined by the chaos edge of the system. The design of proportional-differential controller and phase controller shows the concrete steps and effectiveness of the proposed method.
