Using the input and output signal, the method can model the system, and can control the dynamical property of the system with the inverse transferfunction of the controlled object as the controller.
Through instrumental variable identification method, the single input single output difference equations and the Z transferfunction were gotten.
采用辅助变量辨识方法辨识得到单输入单输出差分方程和Z传递函数。

In transferfunction models these equations are transformed and variables are eliminated between them to find the relation between selected input and output variables.
