control.matlab.nyquist¶
- control.matlab.nyquist(syslist[, omega])¶
Nyquist plot of the frequency response
Plots a Nyquist plot for the system over a (optional) frequency range.
- Parameters
sys1 (list of LTI) – List of linear input/output systems (single system is OK).
... (list of LTI) – List of linear input/output systems (single system is OK).
sysn (list of LTI) – List of linear input/output systems (single system is OK).
omega (array_like) – Set of frequencies to be evaluated, in rad/sec.
- Returns
real (ndarray (or list of ndarray if len(syslist) > 1))) – real part of the frequency response array
imag (ndarray (or list of ndarray if len(syslist) > 1))) – imaginary part of the frequency response array
omega (ndarray (or list of ndarray if len(syslist) > 1))) – frequencies in rad/s
