Question

The controlled variable in a closed-loop system is the direction of a robot arm. Initially, it is at 50o; then it is commanded to go to 25o. What is the error when the arm position is at 15o?a. 15 deg

b. 25 deg
c. 10 deg
d. 35 deg

Answer 1

c. 10 deg

Step-by-step explanation:

Error is the difference between the commanded reference and the actual output, E(s) = R(s) - Y(s)

the measured output is 15°

and the desired output 25°

25 - 15 = 10°
