Lecture #6: Robust performance of the ducted fan

Date: Wednesday, 17 Apr 96

Outline:

A. Ducted fan: performance and uncertainty specification
   1. Transfer function for pitch dynamic
   2. Performance: <= 5% error in tracking up to 5 Hz
   3. Robustness: 20% variation in $r$ (multiplicative)

B. Ducted fan: Controller design and analysis
   1. Lead filter used to get nominal performance, robust stability
   2. Controller does *not* achieve robust performance

Next time: weighted senstivity
