On chaotic observer design

Chaos synchronization is an extremely exciting subject within the physics and communications society and deals with the remarkable observation that certain chaotic dynamic systems exhibit asymptotically identical motion under weak coupling between the systems. Mathematically, synchronization of two systems — sometimes called transmitter and receiver—can be cast in the following form. Given the single output system ∑1 on IR n defined by
$$\sum\nolimits_1 {:\left\{ \begin{array}{l} \dot x = f(x) = f({x_1},{x_2}, \ldots ,{x_n}){x_1}\\ y = h(x) = {x_1} \end{array} \right.} $$
introduce the system ∑2 as a copy of ∑1 with the first state component identical to y, that is
$$\sum\nolimits_{2} {:\left\{ {\begin{array}{*{20}{c}} {\dot{\tilde{x}} = f({{x}_{1}},{{{\tilde{x}}}_{2}}, \ldots ,{{{\tilde{x}}}_{n}})} \hfill \\ {y = h(\tilde{x}) = {{{\tilde{x}}}_{1}}} \hfill \\ \end{array} } \right.}$$
