| Abstract: | Different mathematical models of edge holding force variation are established by fitting edge holding force functions with Lagrangian function interpolation and fitting method and choosing different interpolation points as required by procedures.The optimum mathematical model of edge holding force variation is chosen for variable edge holding force control of digital-controlled hydraulic cushion.The performance and precision are estimated by mathematical calculation. |
