... algorithm is thus adopted in this research to allow rapid control algorithm computation. The employment of MPC on trajectory tracking has been proved effective [ 14–17 ]. Also, as a commonly used process control method, MPC can handle various welding processes as already successfully implemented...

... simultaneously undergoing electric current flow. Using this process, electric current level becomes a new degree of freedom for process control. In this work, we present some alternative control architectures allowing for new avenues of control using such a process. The primary findings are architectures...

.... One of the challenges in THF is the nonlinear and varying friction conditions at the tube-tool interface, which make it difficult to establish accurate loading paths (pressure versus feed) for THF. A THF process control model that can compensate for the loading path deviation due to frictional errors...

...T. A. Palmer; J. W. Elmer Process control in electron beam welding is typically based on control of machine settings, such as accelerating voltage, beam current, focus coil current, and vacuum level. These settings, though important, provide little insight into the characteristics of the beam used...
