| 摘要: |
| 本文所叙述的以eAT为基础的数字仿真方法，是将被仿真系统中的各个连续线性定常部分看作子系统，利用计算机先求出每个子系统的离散状态方程，然后根据各子系统的相互联接、其间的非线性或变系数特性，再进行数字仿真。这种仿真方法计算速度快、精度高、有较强的适应性。
文章中着重介绍了用解析法求解子系统离散状态方程的系数阵。解析法的优点是：对线性定常系统而言，仿真前的计算量及仿真精度与仿真步距 T 的选取无关，其缺点是程序较繁。 |

| Digital Simulation Method on Basis of eAT |

| Abstract: |
| The digital simulation method on basis of eAT presented in this paper consists in treating oarious continuous，1inear，constant parts of the system simulated as subsystems which are desoribed by systems of discrete state equations. Then，these subsystems and various non-linear or time-varying parts are interconnected and thus digital simulation of the whole system is implemented. This method of simulation possesses the merits of fast computing rate，high accuracy and versatilety.
The main point described in this paper is concerning the computation of the coefficient matrixes of the subsystems using analytir method which has the merit in the amount of computation and accuracy of simulation independent of the step size chosen with the (somewhat laboursome) program. |
