:-(Does anybody can help me ? I need some document about trajectory control but I can't find it because I'm not a member of IEEE. Document I need are:
1.T.-C. Lee, K.-T. Song, C.-H. Lee, and C.-C. Teng, “Tracking control of
unicycle-modeled mobile robots using a saturation feedback controller,”
IEEE Trans. Contr. Syst. Technol., vol. 9, pp. 305–318, Mar. 2001.
2.T. Floquet, J. P. Barbot and W. Perruquetti, ”Higher‐order Sliding Mode Stabilization for a Class of Nonholonomic Perturbed Systems”, Automatica, 39, pp. 1077–1083, 2003.
