Abstract:: Aiming to solve the problem of significant soil parameter changes influence the effeiency of Vibra.tion, based on the research into the geological characteristics of ground soil, a new fuzzy controller is de.signed. Based on the on-line adjustment of changing in frequency, this controller has fast and accurate re.sponse and slrong anti-interference ability for the pile hammer in the process of pile driving, "’he purpose ofimproving the working eficieney of the pile hammer is achieved , The simulation and the field test result indi-cate that this parameter self-adjusting fuzzy controller used in the researeh of the on-line identify the frequencyof near-resonant vibration can achieve better result than ordinary fuzzy controller.
