摘要
以五阶和二阶系统为例,利用几种快速积分算法求解系统的微分方程,并比较几种算法的速度和精度,得出一些有益的结论,可直接用于各种仿真器系统,其它实时仿真系统亦可借鉴。
With Euler、Improved Euler、Tustin、2nd order Adams、2nd and 4nd order Runge Kutta fast integration methods,differential equations of 5nd order system and 2nd order system have been solved in this paper.And compared the defferent methods in the aspect of running time and accuracy,some useful conclusions have been obtained,for example the improved Euler method should be used for higher order systems,whether linear or nonlinear,the Tustin method should be used for lower order linear systems.They can directly be used for all kinds of simulator systems while other real time simulation systems can also consult it.
