| 摘 要： | 振动压实中的跳振现象在压实过程中时有发生，跳振现象将造成路基压实质量难以保证，也会对振动压路机操作人员的身心健康产生不利影响。因此，本文从控制“振动压路机-土”系统动力学模型的减振系统阻尼力的角度进行分析，通过研究模糊PID控制和滑模控制对振动控制产生的影响，得到相较于模糊比例积分微分（proportional integral differential，PID）控制，滑模控制可消除系统抖振的影响，更有利于保证路基压实过程中的振动控制，为振动压实的施工作业提供理论支持。

| Abstract: | The jump phenomenon in vibration compaction occurs frequently during the compaction process. Jump phenomenon will cause the subgrade compaction quality, and it will also adversely affect the physical and mental health of vibration roller operators. Therefore, this paper analyzes the damping force of the vibration reduction system from the perspective of controlling the damping force of the vibration roller-soil system dynamics model. By studying the influence of fuzzy proportional integral differential（PID） control and sliding mode control on vibration control, it is obtained that sliding mode control, compared with fuzzy PID control, can eliminate the influence of system chattering, which is more conducive to ensuring the vibration control in the subgrade compaction process and providing theoretical support for the construction operation of vibration compaction. |
