| 摘 要： | 系统传递函数是系统模型的数学形式,广泛地应用于自动控制领域。但由于通过数学建模的形式得到的系统传递函数多与实际情况不符,因此在多数工程中极少运用。通过已知输入信号与输出信号的采样结果,利用矩阵运算与系统辨识技术,客观地求出了系统真实的传递函数并利用Matlab仿真对其进行了验证。经过大量的实践,该技术现已成功应用于实际工程之中。

| Abstract: | The system transfer function is the mathematical form of system model,which is widely used in the field of automatic control.However,the system transfer functions got by the form of the mathematical modeling are inconsistent with the actual situation in most cases,so they are rarely used in most projects.With the known input signal and output signal sampling results,the true transfer function of system is derived objectively by using matrix operations and system identification technology,and verified by mea... |
