提出了一种求解具有常时滞和时变时滞的分数阶非线性微分方程的数值方法。这里的阶数是任意的正真实的数,微分算子是Caputo定义的。将广义Adams-Bashforth-莫尔顿方法与线性插值方法相结合,对分数阶时滞微分方程进行逼近。同时,对该算法进行了详细的误差分析。为了与精确解析解进行比较,数值算例说明了所提方法的有效性。
A numerical method for nonlinear fractional-order differential equations with constant or time-varying delay is devised. The order here is an arbitrary positive real number, and the differential operator is with the Caputo definition. The general Adams-Bashforth-Moulton method combined with the linear interpolation method is employed to approximate the delayed fractional-order differential equations. Meanwhile, the detailed error analysis for this algorithm is given. In order to compare with the exact analytical solution, a numerical example is provided to illustrate the effectiveness of the proposed method.
