【Abstract】 Hydraulic screwdown roll gap regulating device is used on cross wedge mill.Based on the Popov-Landau ’s ultra-stability thorem, a kind of electrohydraulic servo mod-el reference adaptive control system is introduced. The paper gives the algorithm, designmethod, theoretical analysis and digital simulation results,which shows that this controlled sys-tem has good static and dynamic characteristic.The simulation results of the MRAC systemproposed here also show good following and anti-interference ability.The form of the con-troller is easier for field use.更多还原
