Minimal Element Matrix and Observabilities of Nonlinear DEDS
Tao Yue · Systems Engineering - Theory & Practice · 2000
We give the definitions of observability and upper limit observability for nonlinear DEDSΣ:( F( x) ,B,C) .By constructing minimal element matrix Amin= ∧ r∈ Iarij ,using matrix inequality,we give linearization sufficient condition of upper limit obervability,and point out that the upper limit observability is superior to the observability.We also give linearization sufficient condition of individual reachability of sysemΣ .Meanwhile,we discuss the same problems in the dual system ofΣ .
