freson
peak frequencies
Syntax
fr=freson(h)
Arguments
- h
A siso linear dynamical system, in state space, transfer function or zpk representations.
- fr
vector of peak frequencies in Hz
Description
returns the vector frequencies at which the response amplitude of a siso dynamical system is a relative maximum also called resonance frequencies.
Examples
Continuous time system
h=syslin('c',-1+%s,(3+2*%s+%s^2)*(50+0.1*%s+%s^2)); fr=freson(h) clf;bode(h); fig=gcf();sca(fig.children(2)); [phi,db]=phasemag(repfreq(h,fr)); plot(fr,db(:),'+r')

Discrete time system
hd=dscr(h,0.01) fr=freson(hd) clf;bode(hd); fig=gcf();sca(fig.children(2)); [phi,db]=phasemag(repfreq(hd,fr)); plot(fr,db(:),'+r');
