摘      要：The electro-hydraulic servo position control system(HPC) is the core of an auto gap control for a modern four-high continuous hot strip *** actuators are loaded with considerable external disturbances,rolling forces,and the system stiffness and position accuracy will become hypersensitive to the leakage and the compressibility of the *** efforts have being made to increase the position *** conventional resources are proportion-integral-differential(PID) *** the PID controller is faint for a considerable external *** this paper,by introducing the adaptive control strategy of model reference the reciprocities of the system structure with the loads were *** the Lyapunov energy function,an adaptive control algorithm applied to improve the system accuracy was *** system simulations and the selection of parameters of the model were also *** simulations show the static state errors at 0.02%.Finally,the industrial experimental result was given.
