【Abstract】 Taking the industrial computer as the kerne l and employing the ADVENTECH 3 axis servomotor control card PCI 832 as a key co mponent, a high precision control system of digitally controlled positioner for the welding robot is developed. The position controlling accuracy and control p rocess of velocity and movement of the welding positioner are analyzed, and the position responses to the variations in loads and velocities are given, meeting the accuracy requirement during the cooperative process with the arc weld robot.更多还原
