@article{(Open Science Index):https://publications.waset.org/pdf/7029, title = {Nonlinear Fuzzy Tracking Real-time-based Control of Drying Parameters}, author = {Marco Soares dos Santos and Camila Nicola Boeri and Jorge Augusto Ferreira and Fernando Neto da Silva}, country = {}, institution = {}, abstract = {The highly nonlinear characteristics of drying processes have prompted researchers to seek new nonlinear control solutions. However, the relation between the implementation complexity, on-line processing complexity, reliability control structure and controller-s performance is not well established. The present paper proposes high performance nonlinear fuzzy controllers for a real-time operation of a drying machine, being developed under a consistent match between those issues. A PCI-6025E data acquisition device from National Instruments® was used, and the control system was fully designed with MATLAB® / SIMULINK language. Drying parameters, namely relative humidity and temperature, were controlled through MIMOs Hybrid Bang-bang+PI (BPI) and Four-dimensional Fuzzy Logic (FLC) real-time-based controllers to perform drying tests on biological materials. The performance of the drying strategies was compared through several criteria, which are reported without controllers- retuning. Controllers- performance analysis has showed much better performance of FLC than BPI controller. The absolute errors were lower than 8,85 % for Fuzzy Logic Controller, about three times lower than the experimental results with BPI control.}, journal = {International Journal of Mechanical and Mechatronics Engineering}, volume = {4}, number = {11}, year = {2010}, pages = {1163 - 1177}, ee = {https://publications.waset.org/pdf/7029}, url = {https://publications.waset.org/vol/47}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 47, 2010}, }
