Here is some of the homework just to give you an idea Discussion:

– SV has 3 reaction wheels (RWs) where each RW is mounted such that its spin axis is
aligned with the principal directions of the body – RW1 rotates about 1, RW2 spins
about 2, and RW3 about 3 – same as what we derived in class
– = 0.015277 kg ⋅ m2 (reaction wheel MOI about its spin axis)
| 449 0 0 |
– SV_MOI_b [kg-m^2] = | 0 516 0 |
| 0 0 156 |
Step 1) Add the reaction wheel EOM and control law to the code described by a
screenshot from the slide below
“AEE_4807_HW4_2023_Student_Code.m”
Other Information:
– RWmax torque max = ± 0.25 Nm (constraint not currently enforced)
– RWmax speed =± 5,000 RPM (constraint is not currently enforced)
– Quaternion @ = 0, unless directed otherwise, (0) = [0 0 0 1]
– Body-mount radiator normal – 2 (point away from sun and Earth for max efficiency)
– Solar panel normal ― 3 (point towards sun whenever possible)

– Payload boresight 3 (point this axis towards targets)
– Direction of the sun in the inertial frame ― 2
– SV angular velocity at t=0, unless directed otherwise, (0) = [0 0 0]
– RW initial spin rate at t=0, (0) = 2
60[1,000 1,000 1,000] [rad
s ] Control Law
= (1:3) + [rad
2 ] = 50 = 500
CASE 1 – Detumble to Sun Safe Mode
Goal: Detumble SV and get solar panel to point at sun while meeting constraints
Requirements:
(0) = [ ―0.5 ― 0.5 ― 0.5 0.5]
(0) =
180[2 2 2] rad/s initial tumble rate
― 3 axis pointed as best you can towards sun
RW spin rate at t=0 (0) = 2
60[0 0 0] [rad
s ]
Deliverables:
a. Provide a graphical screenshot (main screen)
showing the initial and final SV orientation
b. Plot angle between ― 3 axis and sun vs. time for 1,000 s
c. Write 1-2 sentences for each plot explaining why the plot data proves
you detumbled the SV and the SV achieved the desired attitude
d. Did any reaction violate a torque or angular velocity constraint?
CASE 2 Deliverables – Inertial Hold on Target
Goal: Slew from ICs to attitude listed in the requirements
below
Requirements:
3 axis pointed directly opposite the sun and 2
axis pointed towards ― 1 axis
Initial and Final =
180[0 0 0] rad/s
RW spin rate at t=0 (0) = 2
60[0 0 0] [rad
s ]
Deliverables:`
a. Provide graphical screenshots (main screen with values) showing starting
and final SV orientations and values
