A Spectral Method Based on the Second Kind Chebyshev Polynomials For Solving A Class of Fractional Optimal Control Problems

In this paper, we consider the secondkind chebyshev polynomials (skcps) for the numerical solution of the fractional optimal control problems (focps). firstly, an introduction of the fractional calculus and properties of the shifted skcps are given and then operational matrix of fractional integration is introduced. next, these properties are used together with the legendregauss quadrature formula to reduce the fractional optimal control problem to solving a system of nonlinear algebraic equations that greatly simplifies the problem. finally, some examples are included to confirm the efficiency and accuracy of the proposed method.
