【Abstract】 The pad positioning device in the controllable eccentric stabilizer XTCS can decide the magnitude and direction of eccentric displacement vector.It is difficult to measure the displacement of eccentric vector using the normal sensor,because of the complex structure.The system identification method can be used to determine the displacement of positioning device instead of the displacement sensor.The operation speciality of positioning system was simulated,and a dynamic mathematical model for the hydraulic positioning system of limb was deduced.The identification model was validated by experiment.The actual engineering application capability of the system identification model was evaluated.This method can afford foundation for the use of controllable eccentric stabilizer in XTCS.更多还原
