Friends i have a question related to longitudinal control of an aircraft
Namely i have a longitudinal linear model of F16 and as you know the model is given as steady state

dx/dt = A.x + B.u

where x = [ aircraft velocity angle of attack pitch rate pitch angle] and
u = [ elevator deflection] "the control input

but the model which i have found is given for trim conditions
V= 500 ft/sec
alpha = 3 degree
pitech rate = 0
pitech angle = 3 degree
elevator deflection = -2

i know that this model was obtained after doing linearization about those trim conditions
but if i want to generalize this model , i mean if i want to give another input (elevator deflction ) or if i want to change the speed of this aircraft what can i do? do those equations still be the same or what

please help me
