(8/22 - 8/26)

 HMWK 0: sign up for the
MECH417-L course Listserv

group selection survey sheet
(due Fri, 8/26)

Lab 1 - MatLab (individual)
[see Lab 1 hints]
due Fri, 9/2

2

(8/29 - 9/2)

HMWK 1 (App B and MatLab):
B.1 b, c, d (do b and c by hand;
use integration by parts for c);
B.2 a, c, e, g
(for e use cosine sum trig identity;
do g for for a, c, e only);
B.3 a, b, e (for b, see Equations
B-12 and B-13; do e for a and b only);
B.10 (use Laplace techniques;
a constant forcing function is a step function
starting at time=0;
use Equation B-13 to handle repeated roots)

NOTE - for B.3 and B.10, use partial fraction expansion
to reduce the transfer functions to their most basic forms
before using Appendix C)
due Fri, 9/9

(9/5 - 9/9)

Lab 2 - Simulink (individual)
due Fri, 9/16

4

(9/12 - 9/16)

HMWK 2 (Ch 2):
2.4; 2.5 (Remember that for an ideal op amp, the input currents are zero and the input voltages are equal. Assume ideal op amps.);
2.11 a, b, e (for a, have the source node be 1
and create constants as branches from this single node);
2.17 b; 2.18 b;
2.25 c, d, e (use the block diagram and
definitions for G₁, G₂, G₃, and H provided
in class during the solution to parts a and b);
2.32 (use Equation 2-13 wherever possible)
due Fri, 9/23

5

(9/19 - 9/23)

HMWK 3 (Ch 4):
4.2 (for b, use the closed-loop
K and τ parameters for the sketch)
4.5 (for the sketch, calculate and label
all time-response specs that define
the shape of the response curve),
4.12 (for f, use tf and step),
4.20 (for a, express in
standard second order system form;
for e, use freqs, and abs,
and plot over a frequency range
of 0 to 5 with an increment of 0.1)
due Fri, 9/30

6

(9/26 - 9/30)

7

(10/3 - 10/7)

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))
due Wed, 10/12

8

(10/10 - 10/14)

9

(10/17 - 10/21)

7.3 - 7.5

HMWK 6 (Ch 7):
7.6,
7.7 (for f, in verifying b-e, plot step response
for an example K value in each range to verify
the expected types of response),
7.8
due Wed, 10/26

(10/24 - 10/28)

8.1 - 8.3

11

(10/31 - 11/4)

8.4 - 8.6

HMWK 7 (Ch 8):
8.1; 8.7;
8.12 a, b, c (for b, see Section 8.3.2;
also, the "a" in the exponential should be an "s");
8.16
due Wed, 11/9
(WARNING: please start
this HMWK early)

12

(11/7 - 11/11)

13

(11/14 - 11/18)

HMWK 8 (Ch 9):
9.2 (for a, just use the closest appropriate
table values instead of interpolating);
9.3 (for d, use MATLAB instead of Simulink
and right click on step response plot to add "Characteristics");
9.4; 9.15; 9.20 a, d (also determine the expected
vs. actual settling time; do "d" for "a" only);
9.24 (use a phase-margin frequency of 5 rad/sec,
and determine the estimated and actual settling time)
due Wed, 11/30
(WARNING: please start
this HMWK early)
