摘要
重点讨论了系统的传递函数的性质和复杂机械系统的传递函数表示方法。对复杂系统的传递函数关系作了详细推导和数学运算,并用框图方法表示。用拉普拉斯变换式对微分方程进行变换,把输出和输入联系起来,得到脉冲响应与系统输入输出之间的对等关系。为表示复杂的系统关系提供了一条途径。
The property of transfer function of system and express method of complex mechanical system are discussed. The relation of transfer function of complex system is derived in detail and manipulated with block diagram. Laplace transform is used to combine output and input, then the impulse response and equivalent operations of system input and output are gained. A way is found to denote the relation of the complex system.
