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.
