| Abstract: | Based on the force balance equation of a position control system. a new method is presented which. by using the measured output diagram. load pressure diagram and load pressure-output displacement diagram. can be used to obtain the parameters: static frictional force. frictional force, viscous frictional factor. load stiffness and load mass. The measurement of the hydraulic control system in a testing machine shown that this method is simple. useful and reliable. |
