Introduction• Natural disasters take thousands of lives
every year. • Many first responders perform dangerous
rescue missions to save lives.• Technology will allow first responders to
assess the situation more quickly and efficiently.
3
2012 Colorado Wildfire• The progression of the fire could not be
anticipated.• Once the fire had become an issue, the best
way to access it was unknown.• An autopilot equipped rotorcraft would be able to use a camera and assess the situation.

Why Autopilot?• Easy to use with simple controls• Increase the range of the rotorcraft
– Without autopilot, the rotorcraft must remain in the operator’s line of sight
• A dynamic model is necessary to develop an autopilot
5
System Identification• A dynamic model is a representation of the
behavior of a system (for this case, rotorcraft)• Two options for creating a dynamic model
– System Identification– Wind Tunnel Testing

So, what is System Identification?
SystemInputs Outputs
Given the inputs to a system, a system model can predict the outputs
