摘　　要：本文提出了两种适合于对线性定常系统进行仿真的新算法,它们不仅保持了改进转移矩阵法和拟Adams法的A-稳定性、计算量较小和精度较高等优点,而且弥补了这两种方法在理论上的不严密性和截断误差较大等缺陷,因而具有更好的数值特性,仿真结果表明,文中提出的算法是有效可行的。Two new kinds of algorithms which are suitable for the simulation of linear time-invariant systems are presented. The algorithms not only maintain the good qualities of Modified Transition Matrix Method and Quasi-Adams Method such as A-stability, small computing effort and higher accuracy, but also make up their shortcomings of not strickness on theory and larger truncational error. Thus they have much better numerical properties. Simulation results show that the presented algorithms are feasible and effective.
