本章表明,只要系统是可观测的,就可以使用渐近观测器获得状态x的估计。我们还证明了(n-m)阶观测器足以估计所有状态。我们还定义了一个最小阶观测器来估计状态的线性函数。当只需要一个状态的单一(标量)线性函数时,一个(r-1)阶观测器是可能的,其中r是系统的可观察性指标。
This chapter shows that an estimate of the states x can be obtained using an asymptotic observer whenever the system is observable. We also showed that an observer of order (n-m) is adequate to estimate all the states. We also defined a minimal order observer to estimate linear functions of states. When only a single (scalar) linear function of states is desired, an observer of order (r-1), where r is the observability index of the system, is possible.
