Me kuke so Nyquist Criteria?

Ta'arifin Nyquist Stability Criterion

Nyquist stability criterion yana nufin tattalin rubutu da ake amfani da ita a sayensin kontrol don jin dadin gaskiya na systemi na yanayin.

Amfani da Nyquist Criterion

Yana amfani da shi a cikin systemi na babban rima, kuma zai iya inganta funtunsa da singularities, ba tare da Bode plots.

Formula ta Criterion

Z = adadin root daga 1+G(s)H(s) a hagu na s-plane (Ana kiran shi a cikin zeros of characteristics equation)

N = adadin encirclement daga critical point 1+j0 a nan gaba-gaban saatu

P = adadin poles daga open loop transfer function (OLTF) [i.e. G(s)H(s)] a hagu na s-plane.

Misalai da Nyquist Criterion

Funtunsa da singularities suka bayyana systemi na gaskiya, systemi na baya, da systemi na gaskiya mai karfi a cikin Nyquist plots.

Misalai na Matlab

Kodin Matlab yana taimakawa wajen rubuta diagrams na Nyquist don analisis dadin gaskiya na systemi daban-daban.
