  • Method for controlling pivoting machine member
    Patent number: 6427098
    Abstract: A method and apparatus for control of pivoting machine members propelled by linear actuators so as to permit coordinated motion of the pivoting members with translating machine members. Position commands for the pivoting machine members are given in angular units. The propelling linear actuators are controlled by servomechanism control providing position and velocity control. Position measurements for the pivoting members measure linear displacement of the propelling actuator. Position commands for the pivoting members are compensated according to the non-linear relationship between displacement of the propelling actuator and the angular displacement of the pivoting member.
