Question:
Consider a continuous-time LTI system x(t) = Ax(t), t ≥ 0, with no input (such a system is said to be autonomous), and output y(t) = Cx. We wish to evaluate the energy contained in the system's output, as measured by the index
where
1. Show that if the system is stable, then J( xq) < 00, for any given x0.
2. Show that if the system is stable and there exists a matrixsuch that
then it holds that J(x0) ≤ x0TPx0.
3. Explain how to compute a minimal upper bound on the state energy, for the given initial conditions.
