Lec.- 29 control system gain margin and phase margin for gate ese psu

hello everyone in this lecture about gain margin and phase margin of the system in detail and some examples on gain margin and phase margin..this topic is very important for gate exam,ese exam, ies exam, dmrc exam, net exam and other psu exams. for download pdf notes of this video visit https://www.gate2psu.blogspot.in you can also like us on facebook   / onlinegatecoaching   نيكويست مؤامرة niakwist muamaratan Nyquist հողամաս Nyquist hoghamas Nài kuí sī tè tú 奈奎斯特图 Nyquist ప్లాట్లు A Nyquist plot is a parametric plot of a frequency response used in automatic control and signal processing. The most common use of Nyquist plots is for assessing the stability of a system with feedback. In Cartesian coordinates, the real part of the transfer function is plotted on the X axis. The imaginary part is plotted on the Y axis. The frequency is swept as a parameter, resulting in a plot per frequency. Alternatively, in polar coordinates, the gain of the transfer function is plotted as the radial coordinate, while the phase of the transfer function is plotted as the angular coordinate. The Nyquist plot is named after Harry Nyquist, a former engineer at Bell Laboratories.
