摘要
在自动控制理论中,梅逊增益公式用于求解复杂的信号流图传递函数是很有效的。但求解复杂方块图的传递函数须将方块图转化为信号流图才可应用梅逊增益公式。分析了信号流图与方块图之间的内在关系,对梅逊增益公式中的参数在方块图中进行了定义和说明,定义了方块图中互不接触的概念。提出了直接将梅逊增益公式用于求解复杂方块图传递函数的表述。
In control theory, Mason gain Formula is an effective method in finding the solution of signal flow graph. However, in finding the solution of transfer function of block diagram, Mason Gain Formula can only be used after translating block diagram into signal flow graph. Relation of signal flow graph and block diagram is analyzed. The parameters of Mason Gain Formula in block diagram are defined and explained. The concept of no touch is defined in block diagram. The expression, by which Mason Gain Formula can directly be used in finding the solution of transfer function of block diagram, is provided.
