Abstract
A linear friction welding system and method in one embodiment includes a first motor configured to rotate a first power shaft, a second motor configured to rotate a second power shaft, a memory including program instructions, and a controller operably connected to the first motor, the second motor, and the memory, and configured to execute the program instructions to identify a first current oscillation amplitude of a ram operably connected to the first power shaft and the second power shaft, determine a second desired oscillation amplitude for the ram, determine a minimum shift in relative angle between the first motor and the second motor to achieve the second desired oscillation amplitude, allocate the minimum shift in relative angle between the first motor and the second motor, and control the first motor and the second motor based upon the allocated minimum shift in relative angle.
