大步长、低精度实时仿真积分算法是根据某些应用领域尤其武器研制实际需要而提出来的.目的一般都是为了检验所设计的装置的操作性质.在微分方程(组)求近似解中采用大步长积分是为了加快积分速度, 达到超时要求.而所求解的低精度是基于实时仿真系统的特点.
Abstract
This paper has constructed a class of explicit linear:4-step methods of order 3, and proved their absolute stable range theoretically. In an eigenvalue system withquite large variation. in range of a real-time simulation, the integration speed of this class of methods, is 3 to 7 times faster than that of the practical methods of Adams of order 3.
