Bode criterion

In control theory and stability theory, the Nyquist stability criterion or Strecker–Nyquist stability criterion, independently discovered by the German electrical engineer Felix Strecker [de] at Siemens in 1930 and the Swedish-American electrical engineer Harry Nyquist at Bell Telephone Laboratories in 1932, is a graphical technique for determining the stability of a dynamical system. WebJun 1, 2001 · The Bode diagram is a more intuitive tool for the controller design, however, the Bode Stability Criterion is not applicable to MIMO systems. In this paper, the MIMO Generalized Bode Criterion is ...

Bode plots are used to assess the stability of negative feedback amplifiers by finding the gain and phase margins of an amplifier. The notion of gain and phase margin is based upon the gain expression for a negative feedback amplifier given by where AFB is the gain of the amplifier with feedback (the closed-loop gain), β …

Web4 Bode and Nyquist plots In brief, Bode (rhymes with roadie) plots show the the frequency response of a system. There are two Bode plots one for gain (or magnitude) and one for phase. The amplitude response curves given above are examples of the Bode gain plot. The Nyquist plot combines gain and phase into one plot in the complex plane.
