The paper introduces the operating principle of the village clean tractor electric hydraulic lifting control system,and infers the transfer function of the lifting cylinder.According to using the linear cybernetic theory,the outputing controllability and the observability of the lifting cylinder are analyzed . Basing on these conclusions ,the village clean tractor electric hydraulic lifting fuzzy PID control system is designed.The design has a directive effect on the traditional hydraulic lifting system in automatic control.
