Nonlinear Observer and Its Application(I):Observer for a Class of High-dimensional Nonlinear System

In this paper,a nonlinear observer and the design method of the feedback gain matrix are presented for a class of high-dimensional nonlinear system,which are composed of subsystems whose unmeasured states are coupled in lower triangular form.The observation problem of systems with unmeasured input is further researched,and some considerations for disposing measured variables are discussed for the convenience of observer design.With its ease in design and implementation,the observer can find many applications in chemical processes.
