@article{(Open Science Index):https://publications.waset.org/pdf/69, title = {Hybrid Fuzzy Selecting-Control-by- Range Controllers of a Servopneumatic Fatigue System}, author = {Marco Soares dos Santos and Jorge Augusto Ferreira and Camila Nicola Boeri and Fernando Neto da Silva}, country = {}, institution = {}, abstract = {The present paper proposes high performance nonlinear force controllers for a servopneumatic real-time fatigue test machine. A CompactRIO® controller was used, being fully programmed using LabVIEW language. Fuzzy logic control algorithms were evaluated to tune the integral and derivative components in the development of hybrid controllers, namely a FLC P and a hybrid FLC PID real-time-based controllers. Their behaviours were described by using state diagrams. The main contribution is to ensure a smooth transition between control states, avoiding discrete transitions in controller outputs. Steady-state errors lower than 1.5 N were reached, without retuning the controllers. Good results were also obtained for sinusoidal tracking tasks from 1/¤Ç to 8/¤Ç Hz.}, journal = {International Journal of Mechanical and Mechatronics Engineering}, volume = {4}, number = {11}, year = {2010}, pages = {1240 - 1250}, ee = {https://publications.waset.org/pdf/69}, 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}, }
