摘要：The control accuracy and stability of electro-hydraulic servo force control system will decrease with the change of the control characteristic of system which influenced by different specimen rigidity. First, a mathematical model of force control system considering load rigidity is established, and the influence of the change of load rigidity on the control characteristic is analyzed. Then, a model reference adaptive(MRAC)controller is designed, and a novel reference model which has the characteristics of minimum deadbeat response and strictly positive real has been present. Finally, the performance of minimum deadbeat response MRAC Controller and PID controller have been simulated by Simulink, and constant force speed loading experiments were carried out on the self-made experimental platform by using two specimens with different rigidity. The simulation and experimental results show that the minimum deadbeat response MRAC controller has the advantages of fast response, small overshoot and zero steady-state error, and can effectively restrain the parameter drift of electro-hydraulic servo force control system caused by different specimen rigidity. © 2018, Editorial Department of Control Theory & Applications South China University of Technology.
