Using the value of K_P
computed in Problem 10.18, obtain a plot of the current versus time for a step-command input of 209.4 rad/s (2000 rpm).

Problem 10.18

The parameter values for a certain armature-controlled motor, load, and tachometer are

For the control system whose block diagram is given by Figure 10.3.9, determine the value of the proportional gain K_P
required for the load speed to be within 10% of the desired speed of 2000 rpm at steady state, and use the characteristic roots to evaluate the resulting transient response. For this value of K_P, evaluate the resulting steady-state deviation of the load speed caused by a load torque T_L
= 0.2 N · m.
