Time-delay fractional optimal control problems: a survey based on methodology

We survey some representative results on time-delay frac- tional dierential optimal control problems. In this paper we provide a review of the techniques, developed in the last decade, for the numerical solution of time-delay fractional optimal control problems. In particular, Chebyshev and Chelyshkov wavelet methods, continuous and discrete Chebyshev polynomials methods are focused on this study
