Handout 3: Gain and Phase Margins for unstable systems Eric Feron Feb9,2004 Gain and Phase Margins exist for all systems, including the unstable ones Examplel
Handout 1: Bode plot rules reminder Eric Feron Feb4,2004 General: Bode plot is to plot magnitudes using logarithm scale, phases using log scales. Indeed:
Spring 2003 1661AC22 Longitudinal Dynamics For notational simplicity, let X=Fn, Y= Fu, and Z= F aF Longitudinal equations(1-15 )can be rewritten as mi=X+X2- mg cos(0+△X
Altitude Controller In linearized form, we know from 1-5 that the change of altitude h can be written as the flight path angle times the velocity, so that
