针对线性多变量和单变量系统的控制系统计算机辅助设计，给出从复杂控制系统框图求传递函数的两个算法，对解的存在性进行了讨论，并给出计算实例。该算法适用于对复杂系统稳定性、抗摄动性能等方面的分析和计算。

It is important for computer aided control system design to calculate the transfer function(matrix) from system block description. Two algorithms are introduced in this paper, with the discussion on the existence of the solution. An example is given. The algorithms are applicable to the linear cases of both SISO and MIMO systems, and are valuable for analysis and computation of stability and robustness of complicated systems.
