Fuzzy observer of discrete-time nonlinear systems via an efficient maximum-priority-based switching mechanism

The technical issue of designing a better fuzzy observer is researched by the aid of one so-called maximum-priority-based changing mechanism. More detailed knowledge for some related fuzzy membership functionals can be brought to our main result and a simple but efficient changing mechanism is skillfully exploited. With an extension of the developed changing mechanism to fuzzy observer design, a class of changing-type fuzzy observer is exploited in case of that our obtained error model becomes stable in an asymptotical sense but its conservatism becomes less than previous methods provided in related references. Furthermore, a simple example is presented for the sake of showing our primary benefit in this job.
