One of the most important applications of industrial robots is that of welding. Many such robots use a vision system to measure the performance of the welding. Figure below shows a simplified block diagram of such a system. The welding process is approximated by a second-order underdamped system, the vision system by a unity transfer function, and the controller is assumed to be of the integrator type. Determine the range of values of K for which the closed-loop system is stable Controller Desired welding + R(S) E(S) G.(S)=KU(s) Wire welding process 1 G.
