m_circle

esboça os contornos de iso-ganho y/(1+y) plano complexo

Seqüência de Chamamento

m_circle()
m_circle(gain)

Parâmetros

gain

vetor de ganhos (em DB, decibel). O valor padrão é

gain

=[-12 -8 -6 -5 -4 -3 -2 -1.4 -1 -.5 0.25 0.5 0.7 1 1.4 2 2.3 3 4 5 6 8 12]

Descrição

m_circle desenha os contornos de iso-ganho fornecidos pelo argumento gain no plano complexo (Re,Im).

O valor padrão para gain é:

[-12 -8 -6 -5 -4 -3 -2 -1.4 -1 -.5 0.25 0.5 0.7 1 1.4 2 2.3 3 4 5 6 8 12]

m_circle é utilizado com nyquist.

Exemplos

s=poly(0,'s')
h=syslin('c',(s^2+2*0.9*10*s+100)/(s^2+2*0.3*10.1*s+102.01))
nyquist(h,0.01,100,'(s^2+2*0.9*10*s+100)/(s^2+2*0.3*10.1*s+102.01)')
m_circle();
clf();
s=poly(0,'s')
h=syslin('c',(s^2+2*0.9*10*s+100)/(s^2+2*0.3*10.1*s+102.01))
h1=h*syslin('c',(s^2+2*0.1*15.1*s+228.01)/(s^2+2*0.9*15*s+225))
nyquist([h1;h],0.01,100,['h1';'h'])
m_circle([-8 -6 -4]);
