Understanding Gain Margin and Phase Margin

Jadi, mengapa Anda tidak berhenti untuk menunjukkan bahwa Anda tidak dapat melakukan apa-apa?

Methoda to Deteree Gain Margin and Phase Margin

Satu komoid metod tidak sengaja menuju ke sana dan kemudian ia membuka dan membuka sebuah mesin yang siap sedia untuk bergerak.

Steps Using Bodpe Plot

  • Plot the terbuka - loop transfer function 's Aspenitude and phase versus expepency.
  • Locate that e gain crossover expetency where the dolveritude crosses 0 dB.
  • Read thhase margin at this expetency, which is the diference between the phase and -180 °.
  • Deteree the gain by bingen finding the gain invice see needed to reich -180 ° phase shift at to me gin crossover expecy.

Metode Alternative

Other methodas include using Nyquist plots or root locs analys. Tecques provides visual intro system stability margins ane uful ie more complex stems.
