摘要
Abstract
As an explicit method, the numerical stability of Taylor series method is limited. In simulation of more than one swing or longer time period, the application of high-order Taylor series method has been confined. Based on the recursive calculating of high-order derivatives in the Taylor series method and the multi-step multi-derivative integration formula, a multi-step high-order implicit Taylor series method is proposed, which has both high order and large numerical stability region. It retains the advantages of the original Taylor series method such as accuracy, rapidity and simple recursion and easy programming, and its numerical stability region can include the left half of the complex plane. Numerical examples results show that the algorithm is concise and accurate and effectively improves the numerical stability of high-order Taylor series method.关键词
