Homework Assignment 4
1. Given the time-varying state matrix is the corresponding linear system uniformly exponentially stable? Please detail your rationale; a simple yes/no answer is not sufficient.
2. Determine the values of the parameter α that guarantee that the following linear system is uniformly exponentially stable
3. Suppose v(x(t), t) = xT (t)Qx(t) is a Lyapunov function where Q is constant that proves uniform stability of both ˙(x)(t) = A1 (t)x(t) and ˙(x)(t) = A2 (t)x(t). Show that ˙(x)(t) = (A1 (t) + A2 (t))x(t) is uniformly stable.
4. Consider the time-varying state matrix Show that
the quadratic Lyapunov function obtained from the matrix does not
allow to conclude that the system is uniformly stable, which is instead possible by using the matrix Q = I.
5. Consider the linear state space system
Answer TRUE or FALSE to the following statements and explain your reason- ing. No partial credit.
(a) The system is controllable
(b) The system is observable
(c) The system is (internally) stable
6. Consider the linear state space system
Is the system controllable? Determine an input u(t) that drives the initial condition x(0) = [1, 0]T to zero at t = 1.
7. Suppose the time-varying linear state equation
is controllable on [to ,tf ]. Given arbitrary initial and final conditions xo and xf , respectively, show that there exists a control signal u(t) that transfers the state from x(to ) = xo to x(tf ) = xf .
8. Consider the following four-dimensional linear system.
(a) Study the stability of the linear system. Is the system stable?
(b) Compute the controllability matrix and comment if the system is control- lable.
(c) Compute the observability matrix and comment if the system is observable.
