1. The problem statement, all variables and given/known data
A first-order dynamic system is represented by the differential equation,
\(5\frac{dx(t)}{dt} + x(t) = u(t).\)
Find the corresponding transfer function and state space reprsentation.
2. Relevant equations
N/A.
3. The attempt at a solution
Putting the equation in the Laplace domain yields,
\(5sX(s) + X(s) = U(s)\)
\(\Rightarrow G(s) = \frac{X(s)}{U(s)} = \frac{1}{1+5s}\)
For the state space equations,
\(\frac{dx(t)}{dt} = -0.2x(t) + 0.2u(t)\)
The answer they provide is,
\(\frac{dx(t)}{dt} = -0.2x(t) + 0.5u(t), \quad y(t) = 0.4x(t)\)
How did they 0.5u(t) and how did they know that y(t) = 0.4x(t)?
Thanks again!
