چکیده
Abstract. Aiming at a type of complex nonlinear dynamic systems, a T-S fuzzy control system based on niche model is proposed in this paper. The ecological environment actually occupied by the organism, and the organism’s ability to exploit and use it, is regarded as a unit of a dissipative structure-“niche”. The “costae escarole” theory of niche is used to found a general fuzzy mathematic model. The biological adaptation is combined with the design of fuzzy control system to found a fuzzy inference system and give out a fuzzy T-S model with biotechnology. The measurement of niche is regarded as a consequence of fuzzy control regularity. In this paper, the theoretical proof of this method’s universal approximation is given out, and the method is applied in the control of nonlinear systems. The simulation results suggest this controller is effective.

Adaptive neuro-fuzzy inference system (ANFIS) applied for spectrophotometric determination of fluoxetine and sertraline in pharmaceutical formulations and biological fluid
The UV-spectrophotometric method of analysis was proposed for simultaneous determination of fluoxetine (FLX) and sertraline (SRT). Considering the strong spectral overlap between UV-Vis spectra of these compounds, a previous separation should be carried out in order to determine them by conventional spectrophotometric techniques. Here, full-spectrum multivariate calibrations adaptive neuro-fuzz...
