  1. Gateway To Space ASEN / ASTR 2500

  2. PID Control Law • Proportional, Integral, Derivative (PID) • Used to control single axis • One PID controller for each axis werr Kd tcmd + Rate Gain + + Limiter Att Gain Integrator Limiter Int Att Gain qierr qerr Kp Ki werr = rate error qerr = attitude error qierr = integrated attitude error

  3. PID Control Law Response Times Large Rate Gain = Heavy Damping Small Rate Gain = Light Damping Zero Rate Gain = No Damping

  19. What Did You Do After College? Worked at Lockeed Martin from March 1995 until May 2000

  20. What Did You Do At Martin? - Classified satellite - 1,000 people on program - Youngest - Reaction Control System Mechanical Design Lead - Design done in IDEAS - Released over 100 engineering drawings - Supervised manufacture, assembly, integration and test for 5 satellite builds - Last two years, Mechanical Design Lead for the Antenna systems

  21. What Did You Do At Martin? - Also worked on Stardust and Genesis - Worked with many different disciplines and people

  22. Why Did You Leave? - Many reasons 1. Coming back here was a great opportunity 2. Pictures on the wall 3. Mentor 4. Change
