Najah Yousfi, Pierre Melchior, Chokri Rekik, Nabil Derbel, Alain Oustaloup . Comparison between H8 and CRONE Control combined with QFT Approach to Control Multivariable Systems in Path Tracking Design. International Journal of Computer Applications. 45, 12 ( May 2012), 1-9. DOI=10.5120/6829-9192
Motion control and robust path tracking were the subject of this paper. A method based on fractional prefilter which is extended to multivariable systems is developed. This approach is based on the MIMO-QFT robust synthesis methodology combined with CRONE control. This paper incorporates Quantitative Feedback Theory (QFT) principles to CRONE control design procedure to solve the Two-Degree-Of-Freedom (TDOF) with Highly Uncertain Plants. A comparison between H∞ and CRONE controllers has been done. After that, synthesis of fractional prefilters is given with optimization of its parameters using integral gap criterion. To assess the proposed design, a numerical example has been considered.
