Observability

Observability

1. = Estimate

2. Complete observability

   • if all the states are observable
   • Observability matrix (Q)
     • Range Q = n
       • n= Number of states

3. It is observable

   • At a time t0
   • Determine the value of their initial states x(t0)
     • From the observation of the output y(to)
       • For a finite time

4. Evaluate observability

   • 1. System
   • 2. Matrix form of the system
   • 3. Observability Matrix
   • 4. Different determinant of zero
