6.7.2 Tool
Spectrum analysis tools of “Loop constructor” can analyze and simulate the Nyquist, Bode, and Nichols
diagrams of control system. By using this function, the frequency response of control system can be
obtained.
6.7.2.1 Frequency response function
The frequency response can be expressed by the transfer function of dynamic system, which indicates
the relative relationship between the input signal and the output signal of dynamic system. The control
architecture of drive is shown in figure 6.7.2.1.1.
