Consider the aircraft pitch dynamic system indicated below. Also consider the McDonnell Douglas F-4 data indicated below for flight conditions (H,V)=(35,000ft,584ft/s). θ¨−Mθ˙θ˙−Mθθ=MδEδE (dynamic system) with Mθ˙=−0.307s1,Mθ=−1.927s21,MδE=−4.90s21 a) Compute the θ(t) response expression symbolically for an elevator step δE(t)=δE∗ in terms of parameters Mθ˙,Mθ,MδE,δE∗, and t. Poles within g(s) are known to be complex conjugate roots, as indicated below. Use Pairs #13, \#14 to develop your expression for θ(t). (s2−Mθ˙s−Mθ)=(s2+{2a}s+{a2+ω2})=({s+a}2+ω2)=(s+a−jω)(s+a+jω) b) Using the expression from Part a), plot θ(t) vs. t numerically for an elevator step δE(t)=−3deg for the time period 0≤t≤10s. Overlay the corresponding θ(t) vs. t response from HW \#1 generated by the "lsim" function in Matlab.
