Homework Soursevertical takeoff and landing VTOL a determine the dominant
vertical take-off and landing - VTOL
a- determine the dominant poles of the controlled system
b- complete the parameters of This advance controller for c(S)=pic 4.
Note that: the position response should have a 2% settling time less than 3 sec and not higher elevation on-5%
Solution
The slowest poles of a system (those closest to the imaginary axis in the s-plane) give rise to the longest lasting terms in the transient response of the system. o If a pole or set of poles are very slow compared to others in the transfer function, then they may dominate the transient response. o If we plot the transient response of the system without accounting for the transient response of the fastest poles, we may find little difference from the transient response of the original system.
