App. B

Homework and Lab

HMWK 1 (App B and MatLab):

use integration by parts for c);

do g for a, c, e only);

B-12 and B-13; do e for a and b only);

a constant forcing function is a
step function starting at time=0;
use Equation B-13 to handle repeated roots)

Week

Exam I Review

Ch 6

Homework and Lab

HMWK 5 (Ch 6):
6.1, 6.2 (use the conditions and special cases presented in class),
6.15 (Note – the plant transfer function in the book is wrong. It should be: 0.475 / (s(s^2 + 6s +7.5). In 6.15c, “Steady state oscillation” means “on the verge of instability,” where a pole is imaginary — giving a sinusoidal response –and the 1st column of the Routh Array is on the verge of a sign change. To simulate a PD compensator in Simulink, you can use a PID block, but you must double-click on the block and change the Filter Coefficient (N) from 100 to 1000 to limit its effect.)

9.8 – 9.12

Homework and Lab

HMWK 8 (Ch 9):
9.2 (for part “a,” just use the closest appropriate table values instead of interpolating);
9.3 (Note – the “disturbance torque” is zero for this problem. As indicated, use Hk=1 for the “Sensor,” not the 0.03 shown in the block diagram. For part “d,” use MATLAB instead of Simulink and right click on step response plot to add “Characteristics.”);
9.4
; 9.15 (Note – Figure P9.15 is slightly different from Figure P2.32, so if you use your earlier work from Question 2.32, be sure to modify it to account for the change in Figure P9.15);
9.20 a, d (also determine the expected vs. actual settling time; do part “d” for “a” only);
9.24 (Use Hk=1, as in 9.3. Use a phase-margin frequency of 5 rad/sec. Determine both the estimated and actual settling time. Part “e” should read: “In general, reducing Ki decreases settling time. In those cases, why would an integrator term still be used?”)
