Question
Transcribed Image Text:Consider a dynamic system described by the following second-order
differential equation
ÿ(t)+3y(t)y(t)+y(t)=3sin(t)
with the initial conditions y(0) = 0, and y(0) = 0.
i)
Choose suitable state variables and derive the state space system
model. Give the corresponding initial conditions.
ii)
iii)
dy
- = f (†, y), y(0) = yº, the 4th -order Runge-Kutta method is
dt
given by
Y₁+1=Y₁ + = (k₁ + 2k₂ + 2k3 + k)h
where k; = S(1,93;), k₂ = ƒ{ 1, + ½ h,y), + ½ k;h),
k; = f[ t, + ½ h, y, + — k;h)and k₂ = f(t, +h;y, +k;h).
Using the 4th order Runge-Kutta method and choosing the step
length h = 0.1, find the approximate values of y(t) and y(t) at t =
0.1, and t= 0.2.
