The solution copolymerization of methyl methacrylate and vinyl acetate in a continuous stirred tank reactor is analyzed to illustrate the cognitive model development. Factorial planning was used to discriminate the process variables with higher impact on the process performance (effects) and they are used to built-up a dynamic model based on the functional fuzzy relationship of Takagi–Sugeno type. Gaussian membership functions are considered for the cognitive sets and subtractive clustering method supplied the parameters of the premises of the model. Consequence functions are obtained through an optimization problem solved by a least square based algorithm. The kinetic parameters and reactor operating conditions are obtained from the literature and a mathematical model is considered as plant for identification data generation. Dynamic cognitive models showed satisfactory predictive capabilities and may be an interesting alternative to attack problems of modeling in chemical processes.Submitted by Suelen Reis (suziy.ellen@gmail.com) on 2014-01-13T15:08:18Z No. of bitstreams: 1 10.1002app.25961.pdf: 893791 bytes, checksum: 0a3d77d16363ad07ecd7836917b2104f (MD5)Approved for entry into archive by LIVIA FREITAS (livia.freitas@ufba.br) on 2014-01-20T14:21:01Z (GMT) No. of bitstreams: 1 10.1002app.25961.pdf: 893791 bytes, checksum: 0a3d77d16363ad07ecd7836917b2104f (MD5)Made available in DSpace on 2014-01-20T14:21:01Z (GMT).
