      In this chapter we introduce linear systems (Sec. 3.1) and explore H 2 optimal control problems, including the linear quadratic regulator (LQR) in Sec. 3.2 and Kalman filters in Sec. 3.3. These problems are chosen because of their simplic-ity, ubiquitous application, well-defined quadratic cost-functions, and the existence of known optimal ...

      There is no general procedure for finding the Lyapunov functions for nonlinear systems, but for linear time invariant systems, the procedure comes down to the problem of solving a linear algebraic equation, called the Lyapunov algebraic equation. In view of (4.26a) and (4.26b), a linear time invariant system is stable if one
