WebbControllability Grammian Finite-Time Grammian Cannot be found by solving the Lyapunov equation. Must be found by numerical integration of the matrix-di erential equation: X_ T (t) = AX T (t) + X T (t)AT + BBT from t= 0 to t= T. X c is the steady-state solution. M. Peet Lecture 20: 21 / 24 Webb8.1. Controllability and Observability. We now turn our attention to the design of control systems using state space techniques. The idea is that we measure the state of the system in some way and adjust the inputs to modify the state behaviour. However this implies that we can both observe the states and control them.
