1. The control may be achieved with a DC motor and position feedback of the
system shown below with DC motor and load represented by
where K=2 and p=2. Design a proportional plus derivative controller
to achieve a percent overshoot P.O ≤ 5% to unit step input and a settling time (2%
tolerance) Ts ≤ 2 seconds.
2. Computer control of a robot to spray-paint an automobile is accomplished by the
system shown below:
For the feedback control block of a above spray paint system shown below,
investigate the system when K= 1, 10 and 20. For the three values of K, determine
the percent overshoot, the settling time (with 2% criterion), and steady state error
for a unit step input.
