As the new technology penetrates into the realm of Construction Machinery and the vibratory compaction theory slowly has been perfected and with the application of the new compaction technology and the advanced control technology to the roller, the research of intelligent vibratory roller becomes the focus of the Compaction Machinery. This paper just aims at the frequency control system of intelligent vibratory roller. The paper analyses the various vibratory frequency affecting the compaction, which acts as the basis of the control project of the control system. It analyses vibration hydraulic system of intelligent vibratory roller and builds the maths model of the system. Then, identifying the parameters of the system through least squares and at the same time, optimizing the Proportional-Integral-Differential (PID) parameters by the maths model which has been identified. The paper choose GA(Genetic Algorithms) as the algorithms optimizing the parameters. The result of simulation describes promoting ability of control and the robust of system .Because of the innovation and the time limit, in the paper, the designing PID parameters of the vibration system of the intelligent vibratory roller is still not profound and detail enough and still expect to be improved.
