2
Attitude Control SystemUpdate 6-30-08 Day 32
3

• Control Algorithm
• Turns out our roll determination via B-dot is
  faulty computational error
• Looking at other derivative methods in Matlab

4

• Design Updates
• Mechanical
• Ordered plastic today
• Finishing Solidworks tonight
• Have woodshop access but not mini-shop, need to
  ask Steve to email facilities
• Hardware
• Need different PIC, getting free sample
• Downloading Simulink compiler
• Getting familiar with P-spice

5
Attitude Control SystemUpdate 7-1-08 Day 31
6

• Control Algorithm
• Theory for B-dot failure Coil torques are
  creating instantaneous changes in d2B/dt2 which
  cause large changes in the PID
• Solution Alternate between magnetometer reading
  and attitude control

7

• Design Updates
• Mechanical
• Finished Solidworks! Waiting on plastic now
• Plan to do a Harveys run
• Hardware
• Have the correct PIC
• Working on testing sample code
