摘要
本文提出一种用于线性系统仿真的快速实时四阶龙格-库塔法。这种算法保持了四阶龙格-库塔法精度高的优点.而且数值积分程序计算量小,仿真速度较之一般实时四阶龙格-库塔法可提高约3. 5位。理论分析和仿真实例都说明了这是一种高精度的既快速又实时的线性系统仿真方法。
This paper has deduced and analyzed a fast and real-time algorithm of the fourth-Order Runge
-Kutta(FORK)used to simulate the linear system.This algorithm has maintained the merit of high
precision of FORK and the computing amount of subprogram of its digital integration is small.The
simulation speed increases by a factor of about 4. 5 comparing with the general real-time algorithm of
FORK.According to analysis and practical simulation example.it is shown that this algorithm is high
precision,fast and real-time one in the linear system simulation.
