WebbIn particular, we compute ranks of controllability matrices to determine to what extent different control strategies can suppress alternans. Webb30 juni 2024 · 1 For state space systems, there is a test for 'controllability' involving finding the determinant of a 'controllability' matrix. The instructions for the test is typically to see if the determinant is equal to zero. If that determinant is zero, then the system is said to be NOT controllable.

"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.
