P5.3 A laser beam can be used to weld, drill, etch, cut, and mark metals, as shown in Figure P5.3

(a) [14]. Assume we have a work requirement for an accurate laser to mark a linear path with a closed-loop control system, as shown in Figure P5.3(b). Calculate the necessary gains K and K1 to result in a steady-state error of 5 mm for r t( ) = t mm.
