WebApr 14, 2024 · I want to find the frequency during testing based on the acceleration data collected using accelerometer. I already try several method using MATLAB but I'm not sure if mine is correct. Different method give me different frequency value. For the info, the machine frequency is 6.67 Hz. I attach the code and file for reference. WebCompute the gain margin, phase margin and frequencies. [Gm,Pm,Wcg,Wcp] = margin (sys) Gm = 2.0518 Pm = 13.5634 Wcg = 5.4375 Wcp = 4.3547 The results indicate that a gain variation of over 2.05 (6.24 dB) at the phase crossover frequency of 5.43 rad/s would …

WebMar 22, 2014 · Using MATLAB commands Gp = tf ( [1], [1 1]); [G P] = margin (Gp); My question is what if I want to know the phase over frequency in a specific Gain Over … Webfrequency methods is the relative stability of the system. There are two principal measures of system stability determined via frequency methods: Gain Margin, and Phase Margin. These two measures may be read from Nyquist plots or Bode plots, both of which may be easily constructed using MATLAB. ray white rentals queanbeyan
