In this paper, a fuzzy tracking control strategy for a quad-rotor unmanned aerial vehicle (UAV) with strongly coupling is put forward based on the Takagi-Sugeno(T — S) fuzzy error model. Firstly, The quad-rotor system is divided into altitude subsystem, position subsystem and attitude subsystem, selecting appropriate premise variables, the attitude, altitude and position T — S fuzzy error models are...
The adsorption of acid dyes by diatomite was investigated using Brilliant Scarlet 3R (NSK). Adsorption of this textile dyes onto diatomite earth sample was studied by batch adsorption techniques at varying temperatures 298 K, 309 K, 318 K, 328 K. The adsorption behavior of textile dye on diatomite samples was investigated using a UV-vis spectrophotometric technique. The adsorption processes follow...
